A horny rapper with birds on his back.
Some other people on Urban Dictionary think the Rhymenocerous is or should be specified as not a large, water-dwelling mammal, but this is absurd, because it is well-known that the Hiphopapotamus is the one who finds it necessary to cite the fact that he is not a large, water-dwelling mammal.
