The one thing worse than genocide. One must first have no shame. Then he/she must use a newspaper to find the obituary of a recently deceased man or woman. Then must find a buddy, with no shame, who will aid them in this act. The partners then go to the cemetary where they dig up their victim, and flip a coin. The loser, (or winner depending on how sick you are), applies his/her lips to the genitals or anus of the corpse, while the other partner procedes to climb the nearest tombstone and elbow drop the corpse's stomach. Thus forcing out a blend of rich bodily fluids and embalming materials onto the partners. This blend is called mung. The act of getting this blend on your face is called munging. Chicks'll dig this one.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.

Broadly defined as anything that is very disgusting. Originally from the acronym "Mash Until No Good" from the practice of making many changes to a code until it is useless. Made popular from the Saturday Night Live sketch "Wayne's World", it was in the top 5 worst things to get in your halloween bag. It was mentioned again in South Park episode 317, this time more narrowly defined as a substance which comes out of a pregnant woman's vagina when pressure is applied to her stomach. And somehow an urban legend involving corpse fluids has sprung off the term mung, though there is no documentation supporting that this is anything other than a gross-out story.

Its the stuff that comes out when you push on a pregnant womans stomach
