jacketfiller
A jacketfiller is a fake bouncer who thinks he's the boss. He picks on the weak and runs when trouble shows up. Everyone on the door team hates his guts.
He called a kid a 'weeaboo' and then ran when the kid's friend came over.
He picked on a girl who was barely 16 and looked like she just left school.
He stood there like a chicken when the customer gave him a black eye.
