Top Definition
A hybrid animal with the head of a piranha and the antlers and body of a moose. Kills its prey by goring the creature (or unwitting human) with its horns and then devouring it.

First seen in the webcomic Wondermark, comic No. 495.
Stranger 1: I say, what is that peculiarly formed creature on ye hill over there?

Stranger 2: Not a clue, old chap, but I dare say I shall go and have a closer look at it-AUGH!

Stranger 1: Such cries could only be caused by one creature! The rare and ravenous PIRANHAMOOSE! Run for it!
