crowdie

"a ridiculously passionate and rowdy sports fan, someone who drinks too much at games, screams and shouts at opposing players, hurls obscenities at umpires and referees, wears official team apparel even to work, and lives and dies by how the team is doing."

"I'm not going to any more games with that asshole Steve," Jim complained, "He's too much of a f'n Crowdie and fanboy. I'm sick and tired of getting into fights in the stands."
