Similar to "Take a dump on me". Although instead of having someone's bowels emptied upon you, a homosexual (gay) person is referenced therefore adding the effect of the situation being even worse than when a normal dump has been taken on you.

Larson: Take a gay dump on me!
Benjamin: When and where?
