jacketfiller
A jacketfiller is a door guy who thinks he's cool but can't handle a fight. He hides in the bathroom when things get messy and laughs at the rest of the team when they get beaten up.
I saw the jacketfiller run into the toilet when the bouncer took him down like a dog.
He just stood there grinning when the customer kicked him in the shins.
He picked on a kid who looked like he just walked out of middle school.
