Why English Speakers Say 'Pardon My French': Common Vulgar Expressions Explained

Introduction

As a teenager getting into American culture — rock music, skateboarding, surfing — I kept coming across the phrase “pardon my French,” used right before someone said something rude or vulgar. For years I didn’t really understand the joke. It wasn’t until I started teaching French professionally that it clicked: a striking number of extremely common, everyday French expressions are, translated literally, genuinely vulgar. This article explains a few of the most common ones — not to encourage you to use them casually, but because you’ll hear them constantly in native content, and understanding them is part of understanding real spoken French.

A quick note before we start: these expressions are casual/familiar register. They’re common in everyday conversation, YouTube videos, and shows like Call My Agent! (Dix pour cent in French), but you won’t find them in written journalism or formal contexts.

”Putain”

Literally, putain means “prostitute,” used in a very negative, insulting sense historically. In practice, French people use it constantly as an all-purpose exclamation — functioning almost exactly like “fuck” in English. It can express anger (“putain, la voiture a un problème” — “damn, the car’s broken”), or excitement and surprise (“putain, il a marqué !” — “no way, he scored!”). The meaning depends entirely on tone and context, not on the word itself.

”C’est le bordel”

Literally, a bordel is a brothel. But “c’est le bordel” is an extremely common way to say “it’s a mess” — used constantly, including by parents telling their kids to tidy their room: “c’est le bordel dans ta chambre.” It also works for chaotic situations generally: “il y avait des problèmes de train, c’était vraiment le bordel” (“there were train problems, it was total chaos”).

”Casse-couilles”

This one comes from casser (to break) plus a vulgar word for male genitals — roughly equivalent to “it’s a pain in the ass” or “it pisses me off” in English. Despite the literal anatomy, both men and women use this expression freely. “La conjugaison en français, c’est un peu casse-couille” is a perfectly normal thing to say, even in front of family — it’s vulgar, but not shocking in the way a direct insult would be.

”Ça me fait chier” / “C’est chiant”

Literally, this translates to something like “it makes me poop” — chier being a crude verb for that bodily function. In practice, it simply means “it’s annoying” or “that pisses me off.” You’ll hear a French driver mutter “c’est chiant, il y a des embouteillages” (traffic is so annoying) without any conscious connection to the literal meaning at all — the vulgarity has essentially been bleached out through everyday use.

”C’est chiant à mourir”

Building on the same root, this means “it’s incredibly boring” (literally something closer to “it makes me poop to death”). You could say “on est allé voir le dernier film et c’était chiant à mourir” to friends, or even to your own parents — mildly vulgar, but well within the range of totally normal daily speech.

”Je suis dans la merde”

Literally “I’m in the shit,” this means “I’m in trouble” or “I have a real problem.” It’s used constantly and casually: “j’ai pas fait ma déclaration d’impôts, je suis dans la merde” (I didn’t file my taxes, I’m in trouble). The equivalent English phrase carries roughly the same weight and the same casual usage.

”C’est de la merde”

Similarly, this describes something of poor quality: “j’ai acheté ça, c’est vraiment pas de la bonne qualité, c’est un peu de la merde” (I bought this, the quality isn’t great, it’s kind of crap).

A Superstition Worth Knowing: Don’t Say “Bonne Chance”

Here’s a genuinely useful piece of French culture: before an exam, a job interview, a driving test, or anything similarly high-stakes, wishing someone “bonne chance” (good luck) is considered bad luck. Instead, the traditional thing to say is simply “merde” — the same crude word discussed above, used here almost like the English theatre tradition of “break a leg.” You’ll hear parents tell their kids “merde pour le bac” (good luck on your exam) rather than the literal “good luck.” It’s not a hard rule — nothing terrible happens if you say “bonne chance” instead — but if you want to sound genuinely French, this is the phrase to use.

Why This Matters for Learners

None of this vocabulary shows up in textbooks or structured podcasts made for learners, and for good reason — it’s not something you need to actively produce, especially early on. But if you start watching native French content, a French Netflix show, or a YouTuber you enjoy, there’s a strong chance a good portion of these expressions will show up regularly. Recognizing them — rather than being thrown off by the literal, often absurd meaning — is a real and useful step toward understanding French as it’s actually spoken, not just as it’s taught.

Conclusion

The gap between the “correct,” textbook version of French and how people actually talk day to day is often exactly this: casual, mildly vulgar expressions that have long since lost their literal shock value through sheer repetition. You don’t need to start swearing in French to sound fluent. But understanding why a French person might casually say something that translates to “it makes me poop” when they’re simply annoyed about traffic — that’s a genuinely useful piece of the language, and a good answer to why English speakers have been saying “pardon my French” for so long.
