French Slang: 20+ Essential Words and Expressions

Q: What is verlan and why do French people use it?

Verlan is a form of French slang where the syllables of a word are reversed. The name itself is l'envers (meaning "the reverse") flipped into verlan. It originated in working-class and immigrant suburbs of Paris in the mid-20th century as an in-group code. Verlan exploded into mainstream youth culture through hip-hop, film, and TV in the 1990s and 2000s. Classic examples include meuf (from femme, woman), ouf (from fou, crazy), chelou (from louche, shady), and teuf (from fête, party). Today verlan is a normal part of casual speech for anyone under 40, and some words like meuf and ouf have become so common that they appear in standard dictionaries. Using verlan naturally marks you as plugged into modern French culture and aware of youth speech patterns.

French slang (known as argot or langage familier) is the key to understanding real French conversation. Textbook French will get you through a hotel check-in, but it leaves you stranded at a Paris café when locals say kiffer, bosser, or mec.

Modern French slang comes from many sources. Traditional argot rooted in working-class Paris, verlan (syllable-reversed words like meuf for femme), borrowings from Arabic and North African French, and English words from youth culture all blend together. Formality matters enormously. Using slang with strangers over forty or in professional settings marks you as rude, while using only formal French with friends makes you sound stiff and foreign.

FluentFlash helps you master French slang through spaced repetition with real context notes. You learn not just what a word means, but when and with whom to use it. Below you will find over twenty essential French slang terms with pronunciation, examples, and usage guidance.

Everyday French Slang, Safe for Any Casual Setting

These are the most common slang terms you will hear from French friends, coworkers, and on casual TV. They are informal but not vulgar, and appropriate in any relaxed conversation with peers.

When to Use Everyday Slang

Avoid these words in formal writing, job interviews, or when speaking with elderly strangers. Use them freely with friends, classmates, and colleagues in casual moments.

mec (MEK) = guy or dude. "Ce mec est sympa" means "That guy is cool." Universal and informal, use freely with friends but avoid formal writing.

meuf (MUHF) = girl or woman (verlan of femme). "Ma meuf travaille demain" means "My girlfriend works tomorrow." Very common youth slang. Can mean girlfriend or just "a woman" depending on context. Casual only.

bosser (boh-SAY) = to work (informal). "Je bosse toute la journée" means "I'm working all day." Extremely common. Fine with colleagues in casual moments, but use travailler in formal emails.

kiffer (kee-FAY) = to love or really like (from Arabic kif). "Je kiffe cette chanson" means "I'm loving this song." Youth slang very popular since the 2000s. Casual only, never in formal contexts.

bouffer (boo-FAY) = to eat (slang) or to scarf down. "On va bouffer un kebab" means "Shall we grab a kebab?" Informal and slightly crude. Fine with friends, rude at a dinner party.

Common Filler Words

ouais (WEH) = yeah (instead of oui). "Ouais, je viens" means "Yeah, I'm coming." Universally used in casual speech. Never write it in formal contexts. Always use oui instead.

truc (TROOK) = thing or thingamajig. "Passe-moi ce truc" means "Pass me that thing." Ubiquitous filler word safe in all casual contexts. Avoid in formal writing where chose is better.

bouquin (boo-KAN) = book (informal). "J'ai lu un super bouquin" means "I read an awesome book." Friendly, slightly old-school slang safe across generations.

Money and Work Terms

fric (FREEK) = money or cash. "Je n'ai pas de fric ce mois-ci" means "I'm out of cash this month." Casual but widely understood. Other slang words for money include thune, blé, and pognon. Avoid in business contexts.

boulot (boo-LOH) = job or work. "Je dois aller au boulot" means "I have to go to work." Extremely common across all ages in casual speech. Not appropriate in a CV or cover letter.

Verlan and Youth Slang

Verlan flips the syllables of a word. Verlan itself is l'envers ("reverse") flipped around. It started in suburban neighborhoods and is now mainstream among anyone under 40. Some verlan has even entered standard dictionaries.

Understanding Verlan Structure

Verlan began as an in-group code in working-class Paris suburbs. It exploded into mainstream culture through hip-hop, film, and TV in the 1990s and 2000s. Today verlan is a normal part of casual speech for anyone under 40, and some words have become so common they appear in standard dictionaries. Using verlan naturally marks you as plugged into modern French culture.

ouf (OOF) = crazy or insane (verlan of fou). "C'est un truc de ouf" means "That's insane." Very common and used positively (amazing) or neutrally (crazy).

chelou (shuh-LOO) = shady, sketchy, or weird (verlan of louche). "Ce type est trop chelou" means "That guy is super sketchy." Youth slang that describes people or situations feeling off.

relou (ruh-LOO) = annoying or a pain (verlan of lourd). "T'es relou, arrête" means "You're being annoying, stop." Mild and used among friends, not offensive but not polite.

vénère (vay-NAIR) = angry or pissed off (verlan of énervé). "Je suis trop vénère" means "I'm so mad." Casual youth slang stronger than fâché but not vulgar.

Positive and Social Verlan

chanmé (shahn-MAY) = awesome or sick (verlan of méchant). "Ce concert était chanmé" means "That concert was sick." Youth slang, similar to English "sick" or "dope." Positive and enthusiastic.

teuf (TUHF) = party (verlan of fête). "On fait une teuf ce soir" means "We're having a party tonight." Very common among students and young adults.

zarbi (zar-BEE) = weird or strange (verlan of bizarre). "C'est zarbi, ton histoire" means "Your story is weird." Informal and lighter than chelou.

Term	Meaning	Pronunciation	Example
ouf	crazy / insane (verlan of fou)	OOF	C'est un truc de ouf !, That's insane!

Strong and Vulgar French Slang, Use with Caution

These expressions range from edgy to genuinely vulgar. Many appear in French films, rap lyrics, and casual speech between close friends, but using them wrongly can be offensive or embarrassing. Learn to recognize them, but be conservative about using them yourself until you know the social cues.

Heavy Swear Words to Avoid

putain (pew-TAN) = damn or f*ck (vulgar). "Putain, j'ai oublié mes clés" means "Damn, I forgot my keys." This is the most common French swear word. Used constantly as an exclamation in casual speech but inappropriate in polite or formal contexts. Never use with strangers or in professional settings.

merde (MAIRD) = sht or crap (vulgar). "Oh merde, j'ai raté le bus" means "Oh sht, I missed the bus." Vulgar but common. Also used to mean "good luck" in theater. Avoid with strangers or in professional contexts.

con / conne (KOHN / KUN) = idiot or stupid (vulgar, insulting). "Quel con" means "What an idiot." Vulgar and insulting when applied to a person. The literal meaning is anatomical and very crude. Use with extreme caution.

Milder Vulgar Expressions

ça craint (sah KRAN) = that sucks or that's bad. "Il pleut encore, ça craint" means "It's raining again, that sucks." Casual and not vulgar. Widely used across ages.

se barrer (suh bah-RAY) = to get out, clear off, or leave quickly. "Je me barre, à plus" means "I'm outta here, later." Informal and slightly rough but not vulgar. Common in casual speech.

dingue (DANG) = crazy or nuts. "Elle est complètement dingue" means "She's completely nuts." Not vulgar. Used positively (amazing) or to describe someone eccentric. Universal across ages.

chiant / chiante (shee-AHN / shee-AHNT) = annoying or a pain (vulgar-adjacent). "Ce film est trop chiant" means "This movie is so boring or annoying." Mildly vulgar and derived from chier (to defecate). Fine among friends, avoid in polite company.

Safe Exclamations

la vache (lah VAHSH) = wow or holy cow (literally "the cow"). "La vache, c'est cher" means "Wow, that's expensive." Totally safe exclamation. Use freely in any casual context, even with older speakers.

Term	Meaning	Pronunciation	Example
putain	damn / f*ck (vulgar)	pew-TAN	Putain, j'ai oublié mes clés !, Damn, I forgot my keys!
merde	sh*t / crap (vulgar)	MAIRD	Oh merde, j'ai raté le bus., Oh sh*t, I missed the bus.

Frequently Asked Questions

Is French slang safe to use with French people I just met?

Generally, no. At least not heavy slang. French social codes are more formal than American ones, and launching into argot with someone you just met can come across as presumptuous or even rude. This is especially true if the person is older than you or in a professional context.

Safe first-meeting language stays in the register of standard casual French. Use oui instead of ouais, travailler instead of bosser, and no swear words at all. Once the other person uses slang first, you can mirror them back gently.

Words like truc, boulot, and la vache are mild enough to be safe almost anywhere. But verlan, kiffer, and anything vulgar like putain should wait until you know the person well enough to read the social cues.

What is verlan and why do French people use it?

Verlan is a form of French slang where the syllables of a word are reversed. The name itself is l'envers (meaning "the reverse") flipped into verlan. It originated in working-class and immigrant suburbs of Paris in the mid-20th century as an in-group code.

Verlan exploded into mainstream youth culture through hip-hop, film, and TV in the 1990s and 2000s. Classic examples include meuf (from femme, woman), ouf (from fou, crazy), chelou (from louche, shady), and teuf (from fête, party). Today verlan is a normal part of casual speech for anyone under 40, and some words like meuf and ouf have become so common that they appear in standard dictionaries.

Using verlan naturally marks you as plugged into modern French culture and aware of youth speech patterns.

What are the worst French swear words to avoid?

The heaviest French swear words to avoid in almost all settings are putain (equivalent to fck), con/conne (a crude anatomical insult worse than idiot), enculé (extremely vulgar, roughly "fcker"), and salope (a misogynistic slur).

Putain and merde are used so often as casual exclamations that French speakers barely register them among friends. However, they are still off-limits in formal writing, job interviews, and with strangers, children, or elderly people. Con is particularly tricky because it can be relatively light (quel con = what an idiot) or genuinely offensive depending on tone and context.

Foreign learners should generally avoid using strong swears actively until they have spent significant time immersed in native conversation. Understanding them is essential, but deploying them correctly takes practice.

How do French young people text and chat online?

French youth text using a mix of slang, verlan, abbreviations, and English borrowings. Common text abbreviations include:

slt (salut, hi)
tkt (t'inquiète, don't worry)
jsp (je sais pas, I don't know)
mdr (mort de rire, equivalent to LOL)
ptdr (pété de rire, stronger LOL)
bg (beau gosse, hot guy)

Numbers substitute sounds too. "Koi29" means quoi de neuf (what's new), and "a12c4" means à un de ces quatre (see you one of these days). You will also see heavy verlan, English words like "chill" and "crush," and emoji-driven sentences.

Reading French social media, YouTube comments, and TikTok captions is one of the fastest ways to pick up modern slang in its natural habitat.
