What is scene?

Urban dictionary describes scene as the following:
SCENE
typical "scene" girl: -choppy hair -usually black -septum ring -has a myspace with pictures of her from crazy angles with a TUFF face on because shes so hardxcore -goes to local shows all the time -belongs to a livejournal community called "cuntxcore" or "gungunbangbang" or "murderscene". because anything involving guns, or bang, or murder, or glamour, electric, shock, lust, or cunt, is cool in her book -often says things like "SUP NIGZ" or "KTHXBAI" or "I HATE YOU KDIE" or "IM COOLER THAN YOU K" or "SUP IM RAD" on their myspace profile -loves dinosaurs and robots and little girl bows and headbands because its just the way things are in the scene. dont ask them why all of them happen to find all of these things suddenly attractive, because they dont know themselves, its just what TOTALLY SCENExCORE people do. usually theyre just obnoxious bitches who put on this "scener than thou" attitude and hate everyone else, kthxbai lol.
i am so scene, with my dinosaur shirt and my polka dot headband and my short choppy black hair and my cigarettes and my obnoxious attitude <3 kiss my ass kthxbai see you at the hardcore show tomorrow

TO BE HONEST this creates a negative picture of scenesters and is overall just bitching about scene girls, although some of the stuff is right. Dinosaurs, bows and guns, you gotta love em if you're scene.
