That's an exageration. Other than in an uptight office setting or by the employees in a refined establishment, these words (especially "ouais") are considered familiar but not rude to your interlocutor.

"tromé" might be a bit too young-sounding for general use, but nothing to do with politeness or social class. The well-off Parisian youth love to use these words.

It is certainly isn't an exaggeration. Being familiar to people you do not know is rude: You do not address a stranger with 'tu' but with 'vous', for example.

But 'ouais' is not just familiar, as is in "perfectly fine with people you know", it is lacking manners. Generations of French mothers, teachers, etc. have spent a lot of time scolding children who answered them using "ouais" instead of "oui", as another commenter mentioned. In general it is fine between friends or colleagues, though.

'Putain' is very rude outside of very familiar banter among friends and colleagues.

'tromé', and verlan in general, is quite low social class.

If people here on HN want to learn French then it is obviously useful to know these words but they should not use them. You never get into trouble for speaking properly...

I understand what you're saying, its absence denotes a level of speech that is advised in certain spheres, but describing it as "rude" would be confusing to a non-native. A stranger wouldn't just accidentally drop-in the French "haute-bourgeoisie".

Anywhere else, it is acceptable, don't get offended if someone says those words to you. I have literally heard it used in business meetings with the executives of top funds and companies.

Ouai instead of oui, is like yeah instead of yes. Putain is an interjection of surprise or anger, like when you leave your flat with the door closing behind you only to realize the keys are left inside, that's when you scream putain (fuck). These are not inverse words.

Long story short, most of everything else discussed in this thread is not appropriate. If you address women as meuf (hoe), your friendship and romantic prospects will dwindle like an ice cream under the sun.

If that's how you talk in an interview or on a date, you're out in less than 5 minutes (they may wait the end of hour to show you the door, they are not monster -unlike you-).

It is not acceptable unless you know it is. Saying that using these word is perfectly acceptable is what can only confuse non-native speakers because they then might use them when they shouldn't and then don't understand why they are getting funny looks.

Language in business can be quite spicy but you don't use that language to address your local baker if you have the most basic manners (granted, many people don't).

I agree that non native speakers shouldn't use those words, just because understanding the peculiarities of when it is appropriate is quite difficult.

But those words are, broadly speaking, perfectly acceptable in many situations. Two 20-something or 30-something friends will use "ouais" (and "yeah"), "putain" (and "fuck" or "damn") and even potentially "cette meuf" (and "that dude") without any issue. You wouldn't use those in professional settings in French or in English.

Isn't that exactly what I'm saying? Using those terms between friends (age is irrelevant and those terms are not just for the 'young') may be OK but you would not use them to even talk to a stranger in the street or in a shop if you have basic manners.

[potatoz2]

My main issue is with your use of the phrase "basic manners". This isn't a question of manners. It's like speaking Spanish in a French bakery: it's not rude, it's just not the right context. Similarly if you start vouvoyer your child, it's not "bad manners" it's just not done.

Come on, it's not that bad nor rare. You sound as if you never went out of Paris 16 or Neuilly.
