Get the Bills Mafia mug.
The greatest football fans in the world. It’s a religion in WNY that 30 other cities do not understand. Nor will they ever. The biggest band of brothers and sisters in all professional sports. They always have each other’s backs. They will support their team win or “loose” (Green Bay fan) forever!!! No one circles the wagons like Bills Mafia.
Bills Mafia are so bad ass that one member bit the head off of a bat. Get on the crazy train or get the fuck out of the way.

a bunch of hicks from the Buffalo area that think it is completely fine to make drunken assholes out of themselves and put each other through shitty folding tables (aka Uncle Clem's fancy dining table he stores under his trailer).
NFL Fan #1: Hey, wanna tailgate the Bills game?
