A mythical creature that stalks the internet for its prey of internet spam and online trolls. It has been known to devour entire userpages and will on occasion eat trolling videos. In order to summon a durpivore one must offer an internet troll and play the durp song. It's a distant relative of the jewpacabra.
I was busy trolling on BF3 when I saw this big ass portal open and my character got eaten by something. I swear to God dude it was a durpivore.
