the words gump and tyrannosaurus rex put together. to be gumpy means to look stupid or really goofy or lame. a tyrannosaurus rex is the gumpiest dinosaur ever. so when you call someone a gumpasaurus rex you are saying that they are far beyond being gumpy.
mike: look at josh over there, hes such a weirdo.
sam: wow he looks really goofy, call him over here.
mike: hey you, gumpasaurus rex, come over here!
sam: wow he looks really goofy, call him over here.
mike: hey you, gumpasaurus rex, come over here!

Get the Clitorous Rex mug.
A euphemism for motherfucker, along the lines of sugar honey iced tea, since Oedipus literally was a mother fucker (and a father killer).

That fat bitch is a total Tyqueefosaurus Rex. She sneeze-queefed and the whole car smelled like tuna fish for hours.

A state of drunk where you are feeling great and on top of the world (just like how the T-Rex ruled the dinosaur kingdom) and then the drinks hit you like a meteor and you just become extinct. In certain instances you have T-Rex size cravings and eat massive amounts of awful tasting late night food.
