Slutosaurus Rex 

The largest land penivore of all time. Preys on all types of penises, regardless of shape or size. While larger penises such as the BBC (Big Black Cock) are a difficult prey to take down, the Slutosaurus Rex swallows them with ease; sometimes consuming as much as 4-5 per night to satisfy its massive appetite.

Tyrone: Damn!!! Dat slutosaurus rex swallowed my 9-incher whole!
