look up any word, like cleveland steamer:
Similar to that of mung. Muck however, is the putrid projectile coming out of a deceased mans member (penis) after a violent stomp to his lower abdomen.
The name formally originated when two teenage girls attempted to “Mung” a deceased woman. However the name on the tombstone was androgynous such as the name “Pat.” To their surprise they were about to “Mung” a man. While one of the teenagers stomped on the lower abdomen, the other teen’s mouth was on the ripe decaying penis. She then gargled out the substance and uttered the word “Muck.”

Girl 1: "Howd that taste"

Girl 2: while gargleing the substance "MUCK!"
