Former union guys, who now work at a nonunion shop. They no longer belong to or support the union but still treat nonunion guys like shit. The union calls nonunion guys rats, and they call former union guys queers, fags, and cock suckers hence the name butt
Why do the union, and and the rats call them the butt brotherhood? Because the are trying to screw everyone in the ass.
