Scenesters live to be popular and look down on 'new' kids for not knowing anyone in their scene.
Another notable scenester trait is to make fun of other, more substantial subcultures for being 'old'.
And something about music. I dunno.
"I love the Indie section at Virgin Records,"
"Y'know, I think it's pretty sad that you just won't admit that there's no originality left in the world. That's what I think,"
"When are all these dumb kids gonna grow out of their ideals and just become hipsters already? *sips black coffee*"
