French slang you will hear everywhere, from bouffer to mdr

By the Lingwell team · Updated

The short answer

French slang is informal vocabulary. The Académie française labels bouffer, boulot and fric as Pop. and mec as Fam. It defines verlan as slang that swaps syllables, so louche becomes chelou. It treats mdr as short for mort de rire, and says abbreviations depend on the situation.

French slang is the informal French that people speak and text but that school books skip. This page covers everyday slang words from France, a short look at verlan, and the texting codes such as mdr. For the polite basics, start with common French phrases. For how Québec differs from France, see Quebec French vs France French and English to Quebec French.

What is French slang?

French slang is vocabulary that sits below standard speech. French has a word for it: argot. The Académie française dictionary uses short labels such as Pop., Fam. and Argot in front of a definition, and those labels are the quickest way to see that a word is informal [1][2][3][4].

Slang in the French language is not one list. It has three parts that this page takes in turn: everyday informal words, verlan, and text abbreviations. Learn to recognize them first. Use them once you hear how friends use them.

What are the most common French slang words?

Slang for French everyday life starts with eating, work, money and people. The Académie française dictionary marks each of these words, and the label tells you how informal it is.

Slang wordPlain FrenchMeaningDictionary labelHear it
bouffermangerto eatPop. [1]
le boulotle travailwork, a jobPop. [2]
le fricl’argentmoneyPop. [3]
un mecun hommea guyFam. [4]

Each label comes from the dictionary’s entry for that word. The same dictionary adds that mec also meant, in older usage, a man of the underworld, and that today it also names a man in a couple [4]. Context decides which sense you are hearing.

Here are the first three in sentences, each with a recording:

Compare each with its plain partner: for bouffer. The plain word suits any room. The slang word tells people you know the room.

What is verlan?

Verlan is a form of slang that swaps the syllables of a word. The Académie française defines it as an argot built mainly on permuting syllables, to which vowel changes and shortenings may be added [5]. The name is itself an example: the dictionary traces verlan to the phrase “(à) l’envers”, meaning backwards [5].

Its two examples are louche, “shady”, which became chelou, and femme, “woman”, which became meuf [5]. The dictionary does not say how widely each word is used, so treat them as words to recognize before words to use.

The dictionary entry for verlan gives only the two examples above [5]. Lists of "verlan words" elsewhere are not covered by this source, and some of them go out of fashion quickly.

What does mdr mean in French?

Mdr is the French text abbreviation for mort de rire, literally “dead from laughing” [7]. The Académie française describes it as a sigle sometimes used to translate the English laughing out loud [7]. It is a way to say something is funny, much like “lol” in English.

The same Académie page prefers the spelled-out form and lists longer phrases for the same idea, and, as more familiar options, crouler, crever, être plié or se tordre de rire (to double over laughing) [7]. In its dictionary, “être mort de rire” is itself marked fam. [8].

What are common French texting abbreviations?

A French abbreviation in a message works the way English ones do: it drops letters and keeps the sound. Besides mdr, here is some common shorthand, with the spelled-out words [9].

AbbreviationSpelled outEnglish
mdrmort de rireLOL [7]
sltsalut [9]hi
stps’il te plaît [9]please
jspje sais pas [9]I do not know
ptdrpété de rire [9]cracking up

The Académie française was asked what it thinks of such abbreviations in messages, for example aprem for après-midi and mdr. Its answer, from 2016, is that abbreviating is an old technique and that it sees little danger [6]. It adds that the problem starts when someone thinks abbreviated forms are the norm in every situation [6]. In plain terms: fine in a text to a friend, not in a formal email.
