23 French Slang Words To Add To Your Vocabulary

1. Bouffer

Bouffer is a colloquial verb meaning “to eat”.
It literally means to “puff up” or “blow up” in size however it’s common to hear it being used in everyday speech meaning “to eat”.
This led to the introduction of the noun la bouffe which means food.
Example:
- J’ai bouffé à la cantine ce midi. (I ate at the cafeteria at lunch time).
2. Kiffer
This is the trendiest new word used by French-speaking millennials everywhere.
Kiffer is based on kif, originating from the Arabic word ‘hashish’ or cannabis. The modern French slang meaning is to take pleasure in, to be attracted to or to like something.
The association comes from the heightened sensations from this narcotic.
It was introduced by younger generations of Arabic immigrants and found its way across popular cities and now even holds a place in the dictionary.
Example:
- Je te kiffe ! (I like you)
- Tu vas trop kiffer ! (You will like it!)
3. Faire Gaffe
I love this common French slang phrase because it actually means the opposite of its literal translation which is “to make a mistake”. This expression actually means watch out or be careful!
Example:
- Ça peut être dangereux – fais gaffe ! (That can be dangerous – be careful!)
4. Une Bagnole

This is a kind of “hipster” way to say “car”.
Surprisingly there are many ways to say “car” in French, including:
- voiture
- caisse
- automobile
With all this choice it makes the English language seem a bit dull in comparison!
Example:
- Ah c’est une belle bagnole ! (It’s a beautiful car!)
5. Nickel
Nickel is the name of a metal in English, a material known for its smooth and shiny surface. The French took a shining to this word and adopted it into their own language using it to mean “spotless” or “impeccable”.
Example:
- Range ta chambre, je veux qu’elle soit nickel ! (Clean your room, I want it to be perfectly clean!)
6. Sympa
What does sympa mean? Sympa is an abbreviation of sympathique meaning that something or someone is nice or friendly. The French tend to abbreviate many adjectives to give them a cool edge.
Example:
- J'habite un quartier sympa. (I live in a nice area).
7. Balle

Balle would literally translate as “bullet” in its singular form.
In the days before the Euro become the official currency, the French created this slang word to refer to their old currency: the French Franc.
But when the Euro was introduced the word balles seemed to stick around.
Example:
- J’aime ton pantalon.- Merci. Je l’ai acheté au marché pour quinze balles. (I like your trousers – Thanks, I bought them at the market for 15 quid).
8. Envoyer Du Pâté
Envoyer means to send and pâté describes a spreadable meat paste, a word that we have borrowed and continue to use in the English language.
For some crazy reason, this French slang expression means something is “awesome” and is commonly used by teenagers and students.
Example:
- Ça envoie du pâté ! (It’s awesome!)
9. C’est Trop Bien
Trop is often used to say something is more than très (very). It means something like “so” or “too much”. It's often used to exaggerate how great something is.
Example:
- C’est trop bien que tu sois venu ! (It’s so cool you came by!)
10. C’est Chouette
The word chouette is used to talk about something that's pleasing. It’s usually used to describe a person, an object or an event. This French slang expression is only used in a sincere and genuine way.
Example:
- Je trouve cette couleur très chouette. (I find this colour very nice).
11. Un Mec

The word mec is used for guy in a laid back kind of way just like “dude” or “mate” in English. But it also refers to boyfriend.
To be honest it’s so widely used now that it can hardly be described as cool French slang as you’d probably overhear a bank manager or your teacher saying it.
Example:
- Tu viens avec ton mec ? (Are you bringing your boyfriend?)
12. Une Arnaque
This word basically means something is “a rip off” or a “scam”. It’s great Paris slang to use if you are in the centre of the tourist spots in Paris!
Example:
- Cette annonce est une arnaque. (This advertisement is a scam.)
13. Sans Déc
Sans déc means “no kidding”, “no way” or “get out of here!” The French slang translation is far stronger than in English though.
It’s short for sans déconner. The French often shorten certain words which instantly makes them cool and hipster.
It’s considered by many as French vulgar slang, so you’d best use this phrase in casual situations only.
Example:
- Il a sauté d’un immeuble de trois étages et s’est relevé sans une égratignure. Sans déc ! (He jumped from the 3rd floor of a building and stood up without a scratch. No kidding!)

14. Ça Roule
The literal translation would convert to “that’s rolling” in English. But in French, it means “that’s great”, “that works for me” or “I’m happy with that”.
If you really want to sound cool then you can say Ça roule ma poule, a little French slang rhyme that basically means “no worries, honey”.
Among French colloquial expressions, this is definitely a favourite of mine!
Example:
- On se retrouve dans le centre à midi ? – Ca roule ! (Let’s meet up in the centre at noon. – Okay!/That works for me!)
15. Le Pinard

We all know the French can be wine snobs (and quite rightly so!).
The word pinard refers to a really cheap and awful-tasting wine. The French argot term was apparently introduced in the early 1900s when soldiers used to drink a horrible wine that was branded as Pinard..
Example:
- C’est quoi ce pinard ? (What is this [terrible] wine?)
16. Tranquille
Tranquille is an adjective to describe something relaxing or calm.
However, if you hear used as French modern slang in the streets of France in means something like “sure, no probs”.
Example:
- T’as réussi ton exam ? – Tranquille (Did you pass your exam? – Yeah, easy/no problem!)
17. Quoi
This is a very common French slang word that probably doesn’t technically count as slang anymore due to its popularity.
Quoi translates to English as “what”. Recently French speakers have taken to adding quoi to the end of their sentences to add a certain level of emphasis.
The good news is that you can add it to any sentence without sounding wrong so there's no fear of failure! It’s probably the easiest of the slang words in French to test out among your French peers.
Example:
- Il n’avait pas de plan de la ville. Son téléphone n’avait plus de batterie. Il avait oublié le nom de la personne qu’il devait retrouver… Pas de chance, quoi. (He didn’t have a map of the city. His phone was out of battery. He had forgotten the name of the person he was supposed to meet… Tough luck).
18. Bosser

This is an informal way of using the verb travailler or “to work” as we would say in English.
It’s pronounced “buh-say”.
The next time you are having a hectic week try saying something like this …
Example:
- Je bosse comme un(e) taré(e). – I’m working like a crazy person.
19. La Vache !
Une vache is literally a cow but in modern French slang it means “oh my god”.
As you can imagine, French youngsters use it a lot.
In a way, it’s not far off the American expression “holy cow” which you might have heard Bart Simpson fondly use if you tuned into The Simpsons back in the nineties.
Example:
- La Vache ! Tu m’as fait peur ! (Oh my god! You startled me!)
20. Laisse Tomber
This expression means “let it go”. It’s used in a “drop it” or “never mind” sort of way.
Some would say it’s slightly more aggressive than its English equivalent so it’s one of those French slang phrases you probably don’t want to use around people you’re not too cosy with.
It’s actually a great phrase to use talk about learning a language when you can easily tie yourself up it knots trying to explain a simple concept.
Example:
- Laisse tomber, c’est pas grave ! (Just forget it, it doesn’t matter!)
21. #Oklm
This is a phonetic acronym for the phrase au calme, which literally translates to “being quiet”.
More recently, however, it would mean something is calm, chill, or cool in French slag. French rapper Booba introduced it and it took off from there.
This French text slang also makes for a great hashtag, so you’ll see it on French Instagram or Twitter posts all the time.
Example:
- Une belle balade ce soir #oklm (A nice stroll this evening #chilled)
22. T’sais?
This very casual phrase has become so common that it’s hard to imagine life before T’sais.
It means “you know” or “do you know what I mean” and it's something you would add on at the end of your sentence.
English speakers can definitely relate to this one, as we use something quite similar.
Example:
- Non, mais j’en ai marre, t’sais ? (No, but I’m sick of it, you know?)
23. Allez Savoir Pourquoi
To end this list of French slang words, I’ve chosen allez saviour pourquoi because it loosely translates as “God knows why” or “for whatever reason”.
It's used to describe a situation you have absolutely no idea about and it’s one of those French slang expressions that makes you sound really authentic when you speak French.
Example:
- Allez savoir pourquoi j'ai choisi cette dernière expression (God knows why I’ve chosen this as the last expression).
