poseur
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.
