basically someone who pretends to be something just because it's 'in' or 'trendy'. but it is NOT someone who changes their look every so often because the are experimenting and going through that thing called 'self discovery' or 'adolescence'. how to recognize a poseur/poser: if they call you or anybody else one. how to avoid it: just be yourself. don't fit into the stereotype of whatever.
do i really need one?

1) him: ha! look at that poser! that band is a poserband! (thinking: take down that band poster and destroy my cds).
her: *flippy finger*

2) the real poseur/poser: wasn't he punk last year? what a poseur/poser.
