7. BG

If you want to use slang to refer to a hot guy, you can use the acronym BG. BG stands for beau gosse. Be careful, if you use gosse by itself it is slang meaning a child.

  • Il est beau, ce mec. (That guy is good-looking.)

9. Meuf

Similar to the slang word Mec, Meuf can be used to refer to a female. The origination of this word is femme. Meuf can be used as “girlfriend,” but it can also have displeasing connotations depending on the context in which it is used. Meuf can also describe a woman who is sexually desirable.


  • Cette meuf a de trop beaux yeux. (The woman/female has great eyes).

10. Je me casse

If you want to use slang to let someone know that you are leaving a place, use je me casse. You should know that when you use this slang term that you’re borderline rude. It is comparable to saying “I’m outta here!” Also, you can use this term as an insult. Casse-toi is fiercely telling someone “get out of here!” This term can also be used to say, “piss off.” You probably shouldn’t use this slang word everywhere, but if you are in a situation or on the street and want to get your point across, it is useful.


  • Je lui ai dit “Casse-toi !” parce qu’il me saoulait. (I told him to get outta here because he was aggravating).

11. Bouffer

The true meaning of bouffer is to balloon in size or to puff up. But it is now a slang to replace manger (which means to eat) with bouffer. If you hear the term la bouffe it is referring to food.


  • Je suis allé en ville pour acheter de la bouffe. ( I went into town to buy some food.)

12. Laisse tomber

This phrase means “let it go.” If you completely translate the phrase from French it says, “let if fall.” If you are comparing it to English, it is equivalent to saying, “drop it!” It is important to note that in English it is said more aggressively. In French, it is more subtle. The French version of this phrase can also simply mean “never mind.” A perfect time to use this phrase is when talking to someone and they do not understand what you are trying to tell, or you are tired of explaining yourself.


  • J’abandonne, laisse tomber! (I give up, drop it!)
