I have been helping some folks in Brazil associated with our company in their studies of slang in english. I was researching some slang sites and came across this...
mung n. (1) Used quite frequently back in the 1950's. Purported to be the nastiest substance on earth consisting of a mixture of assorted bodily fluids and solids together with fetid pus from a dead man's ear. Political correctness prevents us from describing the ethnic background of the man (ed: ???). The word was used as an insult and was incorporated into a kind of musical ditty sung thus: "You eat MUNG and bark at the moon." Usually "fighting words"!!(2) currently used on the internet to indicate a confusion or deliberate attempt to deceive (usually in relation to an e-mail address or other identification details). circa. (1) 1950's (2) 1990'ish onwards US
I thought "munch the trunch" was pretty humorous as well.
