The not-common-enough practice of going into a graveyard and digging up a freshly decomposing corpse. It is essential that the corpse is in a certain stage of decay, were the organs have liquified and mixed with bodily fluids to form a fleshy soup. This "soup" ferments to produce gases that inflate the stomach of the corpse. Once such a corpse is found the munging can begin. A coin toss determines who does what. The loser of the toss places his mouth over the genitals or anus of the corpse (personal preference), while the winner proceeds to jump on the gas inflated stomach. The pressure should cause a fleshy explosion in the mouth of the loser and any deposits should be consumed (simple etiquette).
