A fork of Rural Dictionary
An extreme moron. This term was not coined by Bugs Bunny, who only used the term maroon, and then only once. Ultramaroon was a favorite term of "The Champ", a longtime Canadian syndicated radio feature.
"The ultramaroon goes for the head fake. Uppercut, straight right, and a flurry to the solar plexus. 'How's that?" -The Champ
