I always thought maroon was actual slang for "idiot", when in fact it was just a cartoon rabbit ironically mispronouncing the word moron.

Bugs Bunny is also the reason "nimrod" has become slang for an inept person. Nimrod in the Bible is a powerful warrior and capable hunter, but Bugs used it ironically against Elmer Fudd.
