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.
