A girl groupie (typical with gauges, colored hair, and piercings) who listens to Metalcore/Deathcore bands such as Attila, Asking Alexandria, Attack! Attack!, Pierce the Veil, Motionless In White, and Suicide Silence. She will try to get with anybody in a local core band and usually is in a different relationship every month.
"Collin don't date Ariel, she is a Core Whore who was just banging one of the members of this stupid metalcore band that opened up for my band last weekend."
