Speaking from experience Becks? How about munging? This is where you and a friend (you need the help of a friend for this one) dig up a fairly fresh corpse, that is complete with hair and skin and stuff, though the more putrid the better for those that are into it, and while one of you assumes the position of catcher, at an oriface of your own volition and prepare to consume what ever is ejected upon your friend jumping on the soft bit between the ribs and the pelvis. Can be quite messy I'd imagine.
