look up any word, like jamflex:
someone who likes to mung with asses.
"You are an assmung".

a) n. Any secretion from the ass.
b) n. The ooze that comes out of a dead womans ass when you go munging.
When we went double mung-jumping I got stuck with the ass mung while my buddy got to do the bouncing.
