Gruntosaurus Rex

taking a dinosaur-sized crap; would win the "shit of the year" contest; the kind of dump where you lose weight.

After not crapping for a week, I sat down and loaded up the bowl with a Gruntosaurus Rex.

grumpasaurus

a grumpy person. may or may express said grumpiness with non-human like grunts and sounds. definitely pouty and brooding.

An unexpected snowstorm in April turned Graham from a happy, human boy into a decidedly brooding grumpasaurus.

grumpasaurus rex

One who is dour on a colossal scale.

Person 1: "What's wrong with Bill today?"
Person 2: " He lost his wallet this morning and all afternoon he was nothing but a Grumpasaurus Rex to everyone in accounting."

Grumpasauras

Grumpy in a cute, set-in-your-ways kind of way.

gumpasaurus rex

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!
