A Dipladonkis is a fictional creature that has a centaur's body shape, but resembles Barney the dinosaur. (purple and green colors) The creature's mouth is a butt which it eats with, craps out of, and farts with. Dipladonkis is more commonly associated with people who like big butts.
Oh man, you are a total Dipladonkis! I saw you lookin at that big round butt!
