The inner sanctum of the rectal passage.

"Stick a plug in your bumcave, its dripping"
"Where's the tv remote? Is it in your bumcave?"

When three gay men are slamming each other so hard that two of them have to vacuum all of the shit out of the other homo's ass hole while the third faget litterly head fucks a guy and shoots jizz into one of the fagets nostrole
