French Curse Words: Bad Words & Insults in French

Cursing in French

When you’re out in the real world, it can be important to know curse words in case someone ends up using them against you or you need to use them on someone else. Some people also like to sprinkle their conversations with curse words to add or subtract personality to what they’re saying.

Whatever your motivation may be, we’re here now to learn these words!

There’s a lot more that goes into cursing than you think: frequency, severity, gender, etc. And on top of cursing, there is overlap with insults and other bad words.

In this article, we’ll break down the most common curse words, bad words, and insults in French along with their meaning and just how bad they are to use. That way, you understand what’s going on or you have them at the ready in case you need them.

The Most Common Curse Words in French

To start out, you need to know the French curse words you’ll hear most often, so you know what’s going on around you.

In the list below we’ll cover the 20 most common curse words in French ranging from very common to very offensive.

Merde

• Translation: Shit
• English Equivalent: Shit
• Severity: Mild

Merde literally translates to “shit” in English and is used the same way. For example, someone might say “Merde ! J’ai oublié mes clés,” meaning “Shit! I forgot my keys.” Merde can be used to express disapproval or critique as well, like with “C’est de la merde,” translating to “That’s shit.”

While widely used in informal speech, it remains a vulgar word, so it’s best to avoid it in formal situations or with people you don’t know well. Nonetheless, in most casual circles and even just out walking in the street, its widely accepted and very common to hear.

Putain

• Translation: Whore
• English Equivalent: Damn / Shit
• Severity: Mild

Putain is a term that literally means “whore,” but in everyday language, it’s most often used as an expletive like “damn” or “shit.” It’s extremely versatile and can express a wide range of emotions, including frustration, surprise, anger, or even amazement. For example, someone might say “Putain, il pleut encore !” meaning “Damn, it’s raining again!” Despite its crude origin, putain has become so commonly used in casual speech that many French speakers use it reflexively. It can also appear as emphasis in phrases like “Putain de merde !” which can roughly be likened to “f**king shit” or “God dammit.” So while very common and not necessarily offensive, try to keep it out of formal settings.

Bordel

• Translation: Brothel / Whorehouse
• English Equivalent: Crap / Chaos / Mess
• Severity: Mild

Bordel used to refer to a brothel at its origin, but in everyday language it’s most often used as a slang expression to describe mess, crap, or something ridiculous. It’s considered informal and somewhat vulgar, though not as harsh as some other French swear words.

For example, if a child has a messy room, the parent will very likely say “C’est quoi ce bordel ?” applied in the sense of “What’s all this mess?”

While it does have vulgar origins, “bordel” is commonly used in casual conversations and has become a fairly standard way to talk about chaos or mess, though it’s still best avoided in formal or professional contexts.

Chiant

• Translation: Shitty
• English Equivalent: Annoying / Pain in the ass
• Severity: Mild

Chiant is a vulgar but very common slang word used to describe something or someone that is really annoying or a pain in the ass. It comes from the verb “chier” (to shit), which gives it a crude edge, but it’s widely used in everyday conversation, especially among friends or in informal settings.

For example, saying “Il est chiant” means “He’s a pain in the ass.” It’s a useful word to express frustration or boredom with something that’s tedious or irritating. And while it’s not as harsh as some stronger curse words, “chiant” is still considered impolite and informal.

(Ferme) Ta gueule!

• Translation: (Shut) your muzzle / (Shut) your mug
• English Equivalent: Shut the f**k up / Shut your damn mouth
• Severity: Medium

The French phrase “Ta gueule!“, or its longer form “Ferme ta gueule“, is a very rude and aggressive way to tell someone to “shut up.” Less harsh options for saying “shut up” include “Tais-toi” or “Ferme la bouche.”

The word “gueule” is what adds the severity, since it translates to a muzzle (an animal’s mouth). While this phrase appears in movies and is used among friends, in actual conversation it can easily escalation tensions or cause offense.

Casse-toi!

• Translation: Break yourself
• English Equivalent: f**k off / Get lost
• Severity: Medium

The French expression “Casse-toi” is an informal and more aggressive way of telling someone to go away. It uses the verb “se casser” which colloquially means “to leave” or “to take off.”

When you apply the verb to someone else, you’re telling them to “Get lost” or “f**k off” depending on the tone and context. This expression is typically used in moments of anger, frustration, or conflict, and isn’t suitable for polite or formal conversation since it can easily offend.

Casser les couilles

• Translation: Breaking my balls
• English Equivalent: Piss someone off
• Severity: Medium

The French expression “Casser les couilles” translates to mean “Breaking my balls.” It’s a very vulgar and colorful expression used to say that someone or something is pissing someone off. It can be used about people, situations, or things.

For example, “Il me casse les couilles” means “He’s really pissing me off.” Because “couilles” is the informal word for testicles in French, this phrase is considered crude, so it’s best reserved for casual conversations among friends or in heated moments. It’s definitely inappropriate in formal or polite contexts but it is very common in everyday French slang for emphasizing irritation or frustration.

Chier

• Translation: To shit / To crap
• English Equivalent: To shit / To crap
• Severity: Medium

Chier is a very vulgar word that literally means “to shit” and is used in the same literal sense in English. While its literal meaning refers to defecation, in everyday informal speech, it’s often used in a wide variety of phrases to express frustration, annoyance, or contempt. For example, “faire chier quelqu’un” means “to piss someone off.”

If you want to say you’ve been having a hard time, you can say “J’en ai chié.” Or if you want to yell at someone, you can say “Va chier !” or “Screw you!” Because of its graphic and crude nature, chier is not appropriate in formal contexts, but it’s widely used in colloquial speech, especially among friends, in arguments, or in moments of strong emotion. Despite its vulgarity, it’s a highly expressive verb that adds punch and raw emotion to everyday French.

Espèce de + (noun)

• Translation: Species of (noun)
• English Equivalent: f**king (noun)
• Severity: Medium

The French phrase “Espèce de” is an intensifier often used with insults or curse words to emphasize someone’s negative traits. It literally means “species of” whatever word you put after it. So the word “connard” (stupid bastard) becomes “espèce de connard” (stupid f**king bastard), making it stronger and more offensive. It’s a way of making the insult sound more colorful, sarcastic, or biting.

While it’s common in informal banter or arguments, it’s still considered rude and can be very offensive depending on what noun you put after it.

Connard / Connasse

• Translation: Stupid idiot
• English Equivalent: Stupid bastard / Stupid bitch
• Severity: Strong

The French word “connard” (for men) and “connasse” (for women) is a harsh insult that roughly translates to “stupid bastard” or “stupid bitch” depending on the gender. These words are derived from the term “con,” which originally was used to say “pussy,” but over the years has changed to mean something more along the lines of “stupid” or “dumb.”

Connard and connasse today are used as a crude and offensive way to insult someone or call them stupid. It’s frequently heard in the media and everyday arguments, but it’s definitely inappropriate in polite or formal settings, and using it can escalate conflict quickly.

Se foutre de + (noun)

• Translation: To not give a f**k about
• English Equivalent: To not give a f**k/damn about
• Severity: Strong

The French expression “se foutre de” means “to not give a f**k/damn about” something. Depending on how it’s said, “Je m’en fous” can range from casual indifference to open contempt. For example, “Je m’en fous de ce qu’il pense” means “I don’t give a damn about what he thinks.”

While commonly used in anger, it’s still considered crude, especially in formal situations. A softer alternative would be “Je m’en fiche,” which just translates to “I don’t care.” Picking this phrase can cause offense and should be used carefully.

Barre-toi!

• Translation: To leave / To take off
• English Equivalent: Get the f**k away
• Severity: Strong

Barre-toi is the next step up from “Casse-toi,” which we saw earlier. It’s blunt, impolite, and I was warned that using “Barre-toi,” would risk getting into a fight.

While used as a joke among some friend groups, typically this phrase holds a lot of weight and is good to know but should be used sparingly for serious conflicts, since it clearly communicates hostility.

Baiser

• Translation: To f**k
• English Equivalent: To f**k
• Severity: Strong

Baiser has an interesting evolution that has led it to be a harsher curse word today. Historically, baiser simply meant “to kiss”, which we can still see with the noun “un baiser” (a kiss).

However, as a verb, especially in spoken French, baiser now most commonly means “to have sex”, often with a vulgar or crude undertone, similar to the English “to screw” or “to f**k.” For example, “Il l’a baisée.” would mean “He f**ked her.” Because of this shift, most French speakers now use “embrasser” to mean “to kiss” instead. It’s important to know this curse word but not recommended for use in most settings unless you’re using baiser for it’s intended purpose.

Note: Make sure not to confuse baiser, with the verb “baisser” (to decrease). Just a slight difference in pronunciation could change your sentence from talking about a decrease in something to talking about a much more vulgar topic.

Emmerder

• Translation: To piss off
• English Equivalent: To piss off / To f**k with
• Severity: Strong

Emmerder is a vulgar and expressive slang term that’s used to say “to piss off” someone or “to f**k with someone.” It comes from the root word “merde” (shit), which gives it a crude, informal tone. When someone says “Tu m’emmerdes,” they’re saying “You’re pissing me off.”

Though not as aggressively hostile as some other French curse words, emmerder is still impolite and vulgar, and it’s best avoided in formal settings. However, it’s very common in casual speech, films, and literature, especially to express frustration, boredom, or annoyance in a colorful and familiar way.

Salaud

• Translation: Despicable man
• English Equivalent: Bastard / Son of a bitch
• Severity: Strong

Salaud is a strong insult used to describe a man who is considered cruel, dishonest, or morally despicable. It roughly translates to “bastard” or “son of a bitch” in English.

Salaud focuses more on a man’s behavior or character, especially if he wronged someone deeply. For example, “Quel salaud, il l’a laissée tomber !” means “What a bastard, he dumped her!” While it is undeniably vulgar and offensive, salaud is less shocking than some other French swear words and is more commonly heard in movies, literature, and everyday arguments. Still, it remains a harsh insult and is best reserved for strong emotions or fictional settings rather than polite conversation.

Salope

• Translation: Depraved woman
• English Equivalent: Whore / Slut
• Severity: Very Strong

Salope is a highly offensive insult, most commonly directed at women, and roughly translates to “whore” or “slut” in English. It’s one of the most sexist and aggressive curse words in the French language, used to express deep contempt, anger, or hatred.

Calling someone a salope implies not just rudeness or nastiness, but also often carries a sexual insult, accusing the person of being promiscuous or morally corrupt. While it does appear in some films and music about heated topics, it’s extremely disrespectful and should be avoided entirely in most situations. Its impact is severe, and using it can quickly escalate conflict or cause serious offense.

Niquer

• Translation: To f**k
• English Equivalent: To f**k
• Severity: Very Strong

Niquer is a very vulgar slang term meaning “to f**k”, both in a literal sexual sense and in various figurative expressions.

This verb is actually borrowed from Arabic and has become widely used in French street language and pop culture. When used literally, it refers to sexual intercourse in a crude and disrespectful way. Figuratively, it’s often used to express defeat or damage, as in “Je me suis fait niquer” (“I got screwed over”) or “Niquer quelqu’un” (“to mess someone up” or “to screw someone”).

It’s also common in strong attacks, like “Nique ta mère”, which is extremely offensive and translates to “f**k your mother,” but sentences like this may result in a physical fight. Because of its intensity and highly offensive nature, “niquer” should be avoided in most contexts. It’s considered one of the strongest curse words in French, and its use often signals anger, aggression, or rebellion.

Fils de pute

• Translation: Son of a whore
• English Equivalent: Son of a bitch
• Severity: Very Strong

Fils de pute is an extremely vulgar and aggressive expression that literally translates to “son of a whore.” It’s equivalent to “son of a bitch” in English but is often considered more offensive and provocative in French due to its direct attack on someone’s mother.

This phrase is typically used in moments of intense anger, conflict, or insult, and it carries a heavy emotional and confrontational weight. It’s common in street language, fights, rap lyrics, or moments of serious outrage, but it’s absolutely inappropriate in most conversations.

Using fils de pute is seen as deeply disrespectful, and it can escalate tensions quickly or even provoke physical altercations. Because of its severity, it’s one of the most offensive slurs in the French language and should be used with extreme caution, if at all.

Va te faire foutre

• Translation: Go f**k yourself
• English Equivalent: Go f**k yourself
• Severity: Very Strong

The phrase Va te faire foutre is a very vulgar and hostile insult that translates roughly to “Go f**k yourself” in English. It’s used to express strong anger, rejection, or contempt, and is often said in heated arguments or moments of extreme frustration.

Saying Va te faire foutre to someone is considered one of the harshest ways to dismiss or insult someone in French. While it appears in films, music, and street talk, it is absolutely inappropriate in any polite setting. Like its English equivalent, it’s best understood as a full-blown verbal slap. This phrase is powerful, direct, and often intended to provoke or end a conversation in anger.

Enculé

• Translation: Someone who has been anally penetrated
• English Equivalent: f**ker / Motherf**ker
• Severity: Very Strong

Enculé is one of the most offensive and vulgar insults in the French language. The word originally was used to describe someone who had been anally penetrated, but as a curse word it’s used similarly to calling someone a “motherf**ker.”

It’s highly aggressive and deeply insulting. Because of its extreme vulgarity and sexual nature, enculé is considered taboo in polite conversation and can provoke strong reactions, including violence. It’s commonly heard in angry arguments, certain rap lyrics, or very informal, rough contexts. Using this word signals intense contempt and is one of the harshest ways to insult someone in French.

The Most Common Insults in French

While we’re on the topic of bad words, we figured we share some of the most common insults in French as well. Just like with curse words, these could just be for fun or they could be important to know when you hear them. Depending on the culture, some of these may be more offensive than others which is why culture is so important when learning a language.

So if you’re looking to spice up your vocabulary without explicitly using curse words, here are 10 insults you can use in French. Just like with the curse words, we’ve included a translation, the English equivalent, and the severity of the word.

Pauvre

• Translation: Poor
• English Equivalent: Poor
• Severity: Mild

Pauvre means “poor” in all the ways that poor can be applied in English. It can be used to say someone doesn’t have a lot of money. But it can also be used as in “le pauvre” like “poor guy,” when you feel sorry for someone. While this can be used to show sympathy, it’s typically used as sarcasm for somebody who’s being dramatic. You can also add it in front of other words as an intensifier. For example, you can see “le pauvre idiot” to say “the poor idiot.”

Taré

• Translation: Flawed / Blemished
• English Equivalent: Crazy / Off your rocker
• Severity: Mild

Taré is a colloquial insult to call someone crazy, mentally unstable, or “off their rocker.” The word taré traces back to meaning a person with a “tare” or defect. While it’s only mildly insulting, it is still considered rude and offensive, especially if directed at someone in a serious context, as it implies a mental or psychological defect. Its severity varies depending on tone and context, ranging from joking among close friends to genuinely aggressive or insulting in an argument.

Relou

• Translation: Tactless
• English Equivalent: Annoying
• Severity: Mild

A portion of slang in French is taking a word, cutting it in half, and putting the second part at the beginning of the word. Relou is one of those words, as it’s derived from the word “lourd,” with the second part placed at the front. Lourd could originally be applied to someone who’s “a drag” or who’s “tactless.” But once it’s switched, the word only keeps the meaning of someone being “a drag” aka someone being annoying. Since this is slang, this is an insult usually for informal settings but is common in French and not highly offensive.

Tocard

• Translation: An old horse with no hope of winning
• English Equivalent: Loser
• Severity: Mild

Tocard is a slang term used to describe someone who’s a loser. Originally in horse racing jargon, tocard is a horse with little chance of winning. The word has since evolved into a broader insult targeting someone’s perceived lack of skill, success, or value. Calling someone a tocard implies they’re not just failing, but pathetically so. Typically it’s used to mock someone’s failed attempts, poor performance, or general uselessness. While this word is rude and not recommended for polite settings, it’s not the most severe insult and may be heard among friends or family.

Bouffon / Bouffonne

• Translation: Clown / Jester
• English Equivalent: Clown / Buffoon
• Severity: Medium

Bouffon (for men) and Bouffonne (for women) are used to call someone a fool, a clown, or a just a direct translation of buffoon. While the words originally referred to jesters, in modern usage these insults carry a strongly derogatory tone. These words are used against people who shouldn’t be taken seriously or to belittle someone who tries to act important or smart but comes off as ridiculous instead. Depending on the context and tone, bouffon(ne) can be lightly mocking among friends or harsh and insulting in an argument, which is why this one was ranked as medium severity. It’s a common insult among younger speakers, especially in urban slang, and is often meant to provoke or dismiss someone.

Lâche

• Translation: Coward
• English Equivalent: Coward
• Severity: Medium

Lâche literally translates to “coward,” and is applied the same way. Calling someone a lâche implies they run from conflict, betray others to save themselves, or avoid standing up for what’s right. It’s a morally charged insult that attacks a person’s character rather than their intelligence or competence. While not vulgar, it is quite severe emotional attack, especially in confrontations. Being called a lâche in French culture can be deeply offensive, as bravery and honor are culturally valued traits.

Con / Conne

• Translation: Pussy
• English Equivalent: Idiot / Stupid
• Severity: Medium

Con (for men) and Conne (for women) are amongst the most common and versatile vulgar insults in French. This word is used both as a noun (idiot) and an adjective (stupid or dumb). While the literal root of con is a vulgar term for female genitalia, in modern usage it has largely shifted just to insulting someone’s intelligence and is less taboo in France than its literal translation would be in English-speaking countries. It’s frequently used in everyday speech, often with varying levels of intensity depending on tone and context. A common phrase when you’re mildly frustrated is, “Mais t’es con ou quoi ?” or “Are you stupid or what?” However, saying direction to someone that they’re con(ne) is still offensive unless they know you’re joking.

Débile

• Translation: Idiotic
• English Equivalent: Moron / Stupid
• Severity: Medium

Débile is used to call someone extremely stupid or mentally deficient. While this word once referred clinically to a person with an intellectual disability, today it is a casual but still offensive insult implying that someone is acting ridiculously dumb or clueless. The phrase “Tu es débile” or “You’re a moron,” is a direct and insulting way to criticize someone’s intelligence or behavior. While débile can sometimes be used jokingly among close friends, in most contexts it’s disrespectful and demeaning, especially if said seriously. It remains a fairly strong insult due to its condescending tone and association with mental inadequacy.

Abruti

• Translation: Idiot
• English Equivalent: Idiot / Half-wit
• Severity: Mild

Abruti is used to describe someone as an idiot, half-wit, or someone completely lacking in awareness or intelligence. It comes from the verb abrutir, meaning “to kill off someone’s brain cells.”  Calling someone an abruti is more severe than just calling them “bête” or “dumb.” Instead, it suggests that someone isn’t capable of thinking clearly (maybe due to their dead brain cells) or that they’re just hopelessly stupid. Like many French insults, it can be used either lightly among friends or harshly in arguments, but in serious contexts, it remains derogatory and offensive. For example, saying “Espèce d’abruti !” is a blunt and disrespectful way to call someone out as a total f**king idiot.

Cinglé

• Translation: Crazy / Loony
• English Equivalent: Psycho / Nutcase
• Severity: Strong

Cinglé is used to describe someone as crazy, unhinged, or mentally unstable, similar to calling someone a “nutcase” or “psycho” in English. Derived from the verb cingler (to lash or whip), it originally implied someone had been “whipped into madness.” In modern usage, calling someone cinglé suggests their behavior is irrational, erratic, or over-the-top. It can be used either playfully in cases like, “T’es complètement cinglé, toi !” meaning, “You’re so crazy.” But it can also ramp up to levels of actually calling someone a psychopath and cause problems depending on tone and context. In some contexts, it can also be dismissive or hurtful, particularly if directed at someone struggling with emotional or mental health issues.

Consider This Before Cursing in French

Cursing in another language can be complicated because there can be a lot of factors that influence what is and is not acceptable. In general, cursing is relatively common in French. That being said, there’s a lot to consider before diving head first into spicing up your vocabulary with these words. We broke our suggested considerations into groups below, most of which are considerations you subconsciously make in your native language.

Degrees of Severity

As we listed above, different curse words hold different levels of severity. In English we have fewer curse words and fewer levels of how bad things can get. So really do pay attention to the severity of the words marked above when you’re considering adding them to your own speech. Or gauge your response to these words based on the severity.

Because if someone calls you an “taré,” they’re likely just picking on you, but if someone calls you a “fils de pute” then the conversation will be much different.

Regional Differences

There are 29 different countries in the world that have French as one of their, or the only, official language, not including territories and other countries where French is common but not an official language. Depending on your target country or region, curse words and insults may pack more of a punch. Even within France, certain words may be more common in the north than the south.

So before testing out your new favorite curse word in the French-speaking country you’ll be traveling to, test the waters. Try out different words with a friend from that area, listen to what locals are saying, or try to take in different media from that area to see what curse words are the most common. This could be YouTube, TV, Netflix, whatever you can find to make sure you don’t accidentally offend a native (or start a fight).

Context

Cursing isn’t allowed in every situation, just like in English. Most people don’t go into work throwing curse words around while speaking with their boss. The same applies to French. There’s no problem with cursing while you’re hanging out with friends, and there may be some families that don’t mind cursing either. Cursing is a lot more common in French media than English. And if you’re a football (or soccer) fan, then you’ll have a great place to practice your new words.

Just like in your native language, keep in mind who you’re with and where you are when you put these words to use.

Gender and Social Norms

There may be some curse words that are used more often against one gender than the other. Even though English is less gendered than French, we can still see a gender difference in curse words like “bitch” (typically female) versus curse words like “dick” (typically male). And with these two examples, if we leverage them against the opposite gender, it can hold a whole other level of insult.

Keep that same thing in mind in French as well. Words like “salope” are typically used on females while worlds like “conard” are typically used on males. Small application changes like this can really affect how a curse word is received by the other person.

Your Purposes

Reflect on your own reasons for learning and/or using curse words as well. Are you doing it to spice up your sentences? Or to sound like a local? Are you planning to joke with friends? Or do you need it to yell at someone you’re upset with?

Whatever your reasons may be, keep in mind that there are multiple factors that can convey how you’re using these words. Things like tone and body language can make a huge difference between picking on a friend or starting a fight. All of these factors can make a huge impact on your experience, so keep your intention in mind as you continue on your French journey.
