skeetosaurus rex

A Dinosaur from the Jurassic Period that was the king of the dinosaurs, at least in the department of shooting huge dinosaur loads on other smaller dinosaurs (usually slutty meat eaters.)

Caveman: What happened to you? Another Caveman Covered in Semen: Me hunting and a Skeetosaurus Rex stole my kill, and had his way with me.

Sleeposaurus

When your roommate sleep walks in a drunken stupor, brakes your chess set, and eats all the food that's not his.

#1-Hey man, did you brake my chess set last night?
#2-No, I have no idea what happened to your chess set..
#1-Hmm, okay, well did you eat my food last night?
#2-No, I have no idea what happened to your food..
#3-Looks like Sleeposaurus paid us a little visit last night.
