How pejorative is "frimeur/euse"?
I'm looking for a word to describe someone a bit trashy, vulgar, slightly douchy in an oblivious way - a show-off and also a bit of an asshole. "Frimeur" seems more or less to fit - I have seen in the dictionary that it's pejorative. What are the real-world connotations of this word? How offensive would it be to call someone that?
Any other suggestions? I also thought prétentieux, vulgaire, poseur, vaniteux... but I'm not sure which word captures the essence of what I want the best!
Suggestions welcomed!
