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!

Smarmosaurus Rex 

An alpha breed of Smarmosaur that specializes in being a jerk who tries to get suave with the ladies, but fails due to him not realizing he is coming off as an idiot.

" See that guy Gavin over there? He's known as the Smarmosaurus Rex, he's the only guy who tries that hard to get suave with all the ladies. He's not very likable since he ends up being insincerely ingratiating.

Samosaurous Rex 

A person notorious for being accidentally funny while coming off as an idiot at the same time.

The red-haired clown pussy was making a Samosaurous Rex of himself in the vet clinic. "Stop making a Samosaurous Rex of yourself, Sam!"
