Literally just a scene for the post-MTV generation. Without any real idea of what made the beatniks, hippies or punks so influential, fashioncore kids focus all of their energy and mental capabilities on following clothing trends.
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.
"OMG OMG OMG I can't believe she said that about scenesters! You're UNEDUCATED,"
"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*"
