Faux Pas means literally translated 'False Step'
It is when someone make a 'Social mistake' such as doing something unaccepted or saying something wrong.
"Eric made a total Faux Pas last night when he bought a wine that the host of the dinner party didn't like'
Girl: Can I play the guitar next to Keith in church?
Boy (loudly so that every churchgoer in the congregattion can hear): So you fancy him them?
Now, my boy, that is a faux pas.
Translates directly to false step in French. Translates indirectly to embarrassing social fuck up, which usual makes everything awkward for everybody involved. Major party foul
Man did you see hunter try to make an unwanted move on that girl and get shut down? What a faux pas.
Something some cunt says because they have a superiority complex that involves the complete and utter fucking inability to speak like a normal goddamn human being. The word literally means mistake. That's it. That's all it means. Say mistake, error, fuck up, anything... please. Cunt.
Oh Reginald, I do say, the ball you have thrown in your extraaaavagaaant abode is quite suiting, although I must proclaim, the curtains are definitely a Faux Pas. I apologize for my adamant mouth flatulence, and by apologize, I mean sorry not sorry. For I am better than you, and my choice of drapery would have more beige than your hideous plain Faux Pas white.
