I'm not up on the GAY LINGO, as I am, was, and always will be a straight guy (sorry b........ and p.......), BUT WTF is a "man pussy?"  Some blogger on sodahead was talking about gay marriage and having access to his lover's "man-pussy"??? 

OK...Is "MAN PUSSY" another word for ASSHOLE?

OR does it refer to the MOUTH?

Is this common jargon?  When did this start?
