misplaced jocks, frat boys, or guidos who mosh in hardcore, metal, or punk rock pits and high five after punching little kids and girls in the face. Also partake in chest bumping and are usually far too overdressed for these activities. Spiked hair with large amounts of hair gel or designer hats turned slightly crooked are sure signs you might have found a brocore moshdog in your pit.
An adjective to discribe an act or a person that attempts to look badass and/or hardcore, but instead looks showy, pretenious and lame.
