french slang caution
Yes, I know, you spent hours studying French Slang and Idioms, and they’re so much fun. French schools love to teach idiomatic expressions since it makes for an easy, lively, fun class. But slang is very time sensitive: some expressions are no longer used (you'll sound like an old-timer) and some are exclusively used by teens. Plus, too many idioms will make it look like you're trying too hard.

Be Careful With French Slang

The same caution applies to slang in general. Yes, French people do use a lot of slang: “merde” (shit) is common, so is “con/conne (dumbass, asshole/bitch), “putain” (lit. whore but used for so much more – see video below), and other less-than-charming words.

But what sounds perfectly normal from the lips of a French person, sounds contrived coming from a foreigner.

French Slang May Make You Sound Like a Fool

Furthermore, slang is used in a certain context; if you use it with the wrong people, or in the wrong situation, it will be a big faux pas.

I remember this time when I was having dinner in Boston with a student of mine and his very proper, old-Boston like wife. I was… 25? They were in their 70ies.

I allegedly drank a bit too much wine at dinner, but the wine was good, and I was a bit impressed with the invitation, so I thought wine may help me ease up a bit… and it did. A bit too much.

I was trying to tell a story, and put emotions in it, and at a loss for words I said “it was such a shitty experience”…. The wife said “Of my!” and I realized I was way out of place.

So, choose your “slang” words carefully.

Furthermore, French slang evolves very fast, and you don’t want to be using outdated slang expressions (I said “it’s swell” to my friends one day after reading “The catcher in the Rye”… they had a good laugh)…

Nor should you use too hip sounding ones after a certain age: you’d just sound ridiculous…

Never, Ever Translate French Slang Literally

Never, ever translate a slang expression in another language. What is no big deal in your language may be very offensive in another language.

The literal translation of “con” in French is a 4 letter word starting with a c and ending in a t in English. But the meaning has evolved through time, most French people won’t know the original meaning and we nowadays use “con/conne” all the time.

I’ve known better than to use the English literal translation…

French Slang is Evolving = Do You Know Millennium French Slang?

Understanding slang is however very useful, especially if you enjoy watching French movies or stream French TV.

Check out Olivier’s series of post about “Le Parler D’jeunes“: the current slang expressions of the millennium – mix of verlan, traditional French slang, Arabic, Franglish and new expressions: it’s like a different language.

My Advice About French Slang

My advice: learn slang so you can understand it. But use is sporadically, and only when you are sure the setting and timing are appropriate.

Here is a fun video to illustrate the many uses of the word “putain”. Although quite vulgar, I have to admit the French all use it a lot – well, maybe not my Mom, but I sure do.

Born and raised in Paris, I have been teaching today's French to adults for 20 years in the US and France. Based on my students' goals and needs, I've created unique downloadable French audiobooks focussing on French like it's spoken today, for all levels. Most of my audiobooks are recorded at several speeds to help you conquer the modern French language. Good luck with your studies and remember, repetition is the key!
