-MAN ONLY MOVE- A "stegosaurus" is a type of dick move, much like the batwing or the brain. To successfully do the stegosaurus, you must hair gel your pubic hairs into a mohawk. After drying, lie on your back (fully naked), and get a full on erection. In this postiion, with the mohawked pubes and boner in an upside-down postion, your cock+balls will look like a roughly detailed dinosaur
Jimmy wanted to show his friends the stegosaurus, but he didn't have any hair gel.
