A state of extreme inebriation. Intoxication of the highest order. You want a shit show? You gotta get Dunzo Mumunzo.
"Mumunzo" is derived from the word "Dunzo," which is itself derived from the word "Done" as it applies to varying degrees of drunkenness.
The root phrase is "Dunzo Mumunzo" but "Mumunzo" is a wholly acceptable abbreviation. Get it wet!
"Yo, how done did you guys get last night?"
"We got totally Mumunzo'ed!"
