Placing your flaccid penis into a woman's mouth and bending it in a 'U' shape like a mouth-guard.

A phrase used to describe someone/something that is so gay that normal words dont suffice. The implication is that the person/scenario/object is comparable to being viciously rammed up the down pipe, a situation in which a mouthguard is preferable.
"That pink shirt is really mouthguard dude."
"get your stupid mouthguard dog off me, its trying to roger my drainpipes."
