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."
A group of people, usually women, who get drunk on red wine as a group. The Purpletooth Posse forms at nearly any social occasion where wine is served. Especially popular are "Girls dinners" and "Book Clubs". Can be recognised by glowing purple teethfluttering eyes and slurred speech.
I got home last night and the purpletooth posse was in full effect. I think each of them drank two bottles and not one was making any sense. I just went out to the garage and ignored them.
