A nonsensical phrase uttered at the end of a 'Telephone-pass it on' gossip game/parody in an episode of The Simpsons.

*In "The PTA Disbands", an episode of The Simpsons, Bart attempts to spread "Skinner said the teachers will crack any minute" throughout the crowd of Springfield Elementary School teachers. By the time it reaches Mrs. Krabappel, it has turned into "Skinner said the teachers will crack any minute, purplemonkeydishwasher."

*Taken from Wikipedia

1. A mutant of gentic science, it is a purple-tinted monkey with the body of a dishwasher. Often shouted out in long bouts of silence.

A word that makes you stupid for looking up and completely does not have any purpose what so ever.
