A genre of music that started long ago from the punk movement. Eventually, it died down and now hardcore has become heavily confused with overrated untalented whiny-ass screamo/emo/trendXcore bands such as Atreyu, Norma Jean, and pretty much any other band worshipped by "scenesters"
The birth of REAL hardcore as told by Henry Rollins: That's when that "fuck yeah" guy got a guitar. You know, that guy in the 7-Eleven parking lot who'll look at you and be all like "What the fuck you lookin' at?" That's his band.
FAKE hardcore: Depressing poetry + eyeliner + nail polish + girl's jeans + hair covering one eye + screaming
