bobosaur 

The jizzing Pokemon. Fiendish by nature and highly uncontrollable, the Bobosaur faps on everything and anything out of necessity. If Bobosaur goes too long without fapping, it will spaz out and self-destruct in an explosion of jizz and spikes from it's head.

Bobosaur, I choose you! Bobosaur, use hydro pump... ;)

boobosaurus rex 

noun. A rare species, often found in liberal arts classrooms, malls, gyms, movie theaters, Darque Tans, and other such useless places.

They are characterized by large massive amazing tits and really short skinny arms and bodies. Their enormous boobies often prevent them from walking completely upright and hence they are forced to walk hunched over resembling a tyrannosaurus rex.

Wow id love to cum on that boobosaurus rex's tits.
