Argot et registre familier
Everything you've learned so far is français standard — neutral, written-friendly, polite. Real spoken French — among friends, on social media, in films, in rap — drops several registers below that. The vocabulary changes (mec for homme, bouffer for manger), the syntax loosens (ouais, t'es ouf), whole words get inverted by verlan (femme → meuf, fou → ouf), and a small set of expletives — putain, merde, bordel — pepper conversation as fillers more than insults. Productively learning all of this would take years. The goal here is comprehension — recognize mec, taf, kiffer, chelou when a French friend says them — plus the most important rule of all: register awareness. Argot used in the wrong context (a job interview, a polite dinner, an email to your landlord) makes you sound either rude or absurd. So we cover the words AND when to lock them away.
Verlan — the inverted slang
Verlan (itself the verlan of l'envers = 'the reverse') is the trick of inverting the syllables of a word to make a slang version. It exploded in the 1980s, mostly in the banlieues (suburbs) of Paris, and is now standard among speakers under 50. Many verlan words have become so embedded that even people who'd never speak slang use them: meuf (from fe-mme → meu-fe → meuf) = woman / girlfriend; mec is older argot but the verlan keum also exists; ouf (from fou) = crazy, also as adjective: un truc de ouf = a crazy thing; relou (from lourd) = annoying / bothersome; chelou (from louche) = shady / weird; vénère (from énervé) = annoyed / pissed off; cheum (from moche) = ugly; teuf (from fête) = party; zarbi (from bizarre) = weird; chanmé (from méchant) = wicked, awesome (positive!); cher (from chéri) = darling — wait, that's the opposite direction. Most importantly: verlan is recognizable by sound, not always by spelling, and it carries a clear young/urban/informal flavor — so meuf is fine in any informal setting, but never in a CV or formal letter.
High-frequency familiar vocabulary — the big list
These aren't verlan — just everyday colloquial words that replace neutral ones. mec (m.) = guy / dude; also = boyfriend (mon mec). meuf (f.) = woman / girlfriend (ma meuf). gars (m., gar) = guy. taf = work / job (aller au taf); bosser = to work (je bosse demain). bouffer = to eat (on bouffe au resto?); bouffe (f.) = food / meal (la bouffe est prête). fric / thune / blé / pognon = money. kiffer = to like / love (Arabic origin, kif = pleasure): je kiffe ce film = I love this film. dingue = crazy / amazing (c'est dingue!). chelou = sketchy / weird. vénère = annoyed. balèze = strong / impressive / hard (il est balèze, le mec / l'examen est balèze). flemme (f.) = laziness: j'ai la flemme = I can't be bothered. pote (m./f.) = friend / buddy. boulot = work / job (slightly less slangy than taf). truc / machin = thing / thingamajig. galère (f.) = a drag / mess: c'est la galère = it's a nightmare; galérer = to struggle. chiant = annoying / a pain (mildly vulgar — c'est chiant). nul = lame / awful (c'est nul ce film).
Soft expletives — putain, merde, bordel
France swears fluently and often. The three workhorses are functionally English's 'damn / shit / fuck', but their force depends on context. putain (literally 'whore', etymologically) is the all-purpose intensifier — closer to English 'damn' or 'fucking' in everyday usage, used as a filler, an exclamation, or an emphasis particle: Putain, j'ai oublié mes clés! = Damn, I forgot my keys! C'est putain de bon! = It's fucking good! In Marseille and the south, putain is so common it barely registers as a swear. merde = shit, used like the English: Merde! as exclamation; dans la merde = in trouble; dire merde à quelqu'un = to wish them luck (the theatre tradition, like 'break a leg'). bordel (literally 'brothel') = mess / chaos / 'goddammit': Quel bordel! = What a mess! C'est le bordel = It's a total mess. As an exclamation: Bordel, j'en ai marre! = Goddammit, I'm sick of it! Mais qu'est-ce que tu fous, bordel?! = What the hell are you doing?! Stack them for emphasis: Putain de bordel de merde! = the French triple-stack expletive. None are appropriate at work, in front of children, or with strangers. All are utterly normal among friends.
Texting and chat abbreviations
French SMS / chat language has its own norms. The big ones: slt = salut (hi); bjr = bonjour; bsr = bonsoir; stp / svp = s'il te plaît / s'il vous plaît; mdr = mort de rire (lol — literally 'dying of laughter'); ptdr = pété de rire (lmao); lol is also used; jpp = j'en peux plus (I can't take it anymore); jtm = je t'aime; jsp = je sais pas; dsl = désolé; tkt = t'inquiète (don't worry); mskn = miskine (poor thing, from Arabic); wsh / wesh = hi / hey (greeting, of Arabic origin); rdv = rendez-vous; tlm = tout le monde (everyone); cad = c'est-à-dire (that is to say); bcp = beaucoup; pq = pourquoi; frr / frère = bro; ouf = phew (different from verlan ouf!); bg = beau gosse (handsome guy / 'good-looking'). The 'k' for 'que' is common: kdo = cadeau; koi = quoi; keskecé = qu'est-ce que c'est. Numerals get used phonetically: 2m1 = demain (de-main); a+ = à plus (see ya). All of this is texting/Twitter only — never use it in an email, letter, or anything formal.
Syntactic markers of casual French
Beyond vocabulary, several syntactic features signal familiar register. (1) Dropping ne in negation: j'sais pas = je ne sais pas; t'as pas vu = tu n'as pas vu. Universal in conversation, jarring in writing. (2) Tu → t' before vowel: t'es = tu es; t'as = tu as; t'aimes = tu aimes. (3) Que → qu' before vowel in casual chains: j'pense qu'il vient. (4) Cleft questions: Tu fais quoi? = What are you doing? (Standard: Que fais-tu? / Qu'est-ce que tu fais?). C'est qui? = Who is it? Tu vas où? = Where are you going? (5) C'est for everything: C'est moi qui ai fait ça = I'm the one who did it. (6) Chez nous, ça va le faire, t'inquiète as filler set phrases. (7) Quoi as a sentence-ending tag: C'est cool, quoi. = It's cool, you know? Voilà quoi = There you go. (8) Replacement of nous by on: On y va! = Let's go! — universal in spoken French. None of these are 'wrong' — they're the actual register of native conversation. But they do NOT belong in a formal email, an essay, or a job application.
Register awareness — when NOT to use it
The hardest skill in slang is knowing when to switch it off. As a non-native, the safest defaults: (a) In any professional context — meetings, emails to colleagues you don't know well, job interviews, customer service, banks, doctors, government — stay in standard French. No mec, no bouffer, no kiffer, no dropped ne. (b) With anyone over about 50 you don't know personally, similarly. (c) In writing — emails, letters, documents — keep the register one notch up from how you'd speak. (d) At a polite dinner with family of a French friend, follow their lead: hear how they speak, then mirror. The asymmetric truth: a French speaker peppering an English conversation with 'shit' and 'dude' sounds charming and authentic; a non-native French speaker peppering French with putain and mec sounds like they're trying too hard, especially if their grammar is shaky. So: understand all of it, produce only what fits the moment. When in doubt, drop a register down toward standard rather than up toward street.
Quick recap
(1) Verlan inverts syllables: meuf, ouf, relou, chelou, vénère, chanmé, teuf. (2) Familiar vocabulary: mec, meuf, taf, bosser, bouffer, fric, kiffer, dingue, balèze, galère, flemme, pote, truc. (3) Soft expletives: putain (filler/intensifier), merde, bordel — fine among friends, off-limits at work. (4) Texting: slt, mdr, ptdr, jpp, jtm, tkt, stp, bcp, a+, 2m1. (5) Casual syntax: drop ne, contract tu to t', end with quoi, replace nous by on. (6) Register awareness: comprehend all of it, produce only with people and contexts where it fits. When unsure, lean toward standard French.
