Top Definition
An unfortunate animal. This poor creature appears to be the result of some very peculiar genetic affiliations between an eccentric plattypus, hell bent on assimilating every other species and it's third victim, the donkey. The plight of the donkey as a species is now assured. The plattypus became a demented sexual fiend when it was spawned after the "original" beaver raped a duck.
