Its a pretty obscure subculture *looks down nose* you've probably not heard of them *smug look*
a group of arrogant poseurs who believe themselves to be better than you or me, because the are non-conformist. defined in this case by conforming slavishly to a different group.
they aggresively dislike the term 'Hipster' as they know that it marks them as stupid and moronic, so they call everyone else hipster, kind of like how the most aggresive homophobes call everyone else gay
"oh man, i love 'this band' they make awful music, but no ones heard of them yet. I am such a non-conformist"

"oh man, i hate 'this band' they make good music and everyone has heard of them. anyone who likes them is a Hipster"
