A large group of workers pin down a coworker who has been housin while lacking the authority to do so and the worker asks his "homeboys" not to fuck with him because he is a crazy badass pimp. The coworkers then piss and shit all over him and allow a homosexual colleague to fuck his asshole.
Jon: hey bitch go clean the fucking toilet.
Aaron: fuck you I'm tired of your shit don't make us dirty allen you.
