When a guy comes back from the gym all grimy and sweaty, and makes his boyfriend go to work on his (sexual) plumbing while wearing the plumber jeans that show off the top of his ass crack. Usually, but not always, a handjob.
Dan: Wanna go out tonight?

Nas: Nah, I just don't think I can respect you anymore, since you gave me that rusty plumber earlier.

Joe: You guys are so gay.
