A person that listens to fake, and horrible music that takes no musical talent what so ever. Thinks that he/she can fight...but really can't at all. Usually gets the fuck beat out of them by metalheads who see them "hardcore dancing" in places that are meant for MOSHPITS.
hardcore kid: DUDE I AM SO COOL WACH ME PULL THESE AWESOME WINDMEELS AND THEN RANDOMLY SWING MY ARMS LIKE A MONKEY.
Metalhead: No, fuck you. *knocks em' the fuck down, then continues to mosh on their face.*
