The act of wasting someone where their arms tense up to the point where they become incapacitated and wave around aimlessly like that of a T Rex (Dinosaur)

T Rex is a specific type of handjob, where the person giving a handjob tucks their elbow into the sleeve of a short sleeve shirt, and proceeds to pleasure a man's penis with only their index and middle fingers and their thumb.

When your lady is in the "reverse cowgirl" position, you put clench your hand with the middle knuckle raised (similar to the frogging punch). With this protruding knuckle you then place it on her spine and rub back in forth. The feeling is very intense/ticklish. It will cause her to moan in a weird fashion and her arms will become incapacitated past the forearms for a brief moment.
Some women also seem to do weird things with their mouths during the moment.

A girl that when drunk is half human half dinosaur. She walks, eats, throws up and even growls like a T Rex. Nothing stands in her way when she has the late night munchies. A girl in her mid 20's that takes down a whole crock pot of velvetta cheese dip and a large pizza in one afternoon. A girl who tries to talk while she eats but sounds like a T Rex on a man hunt.

An expression reminiscent of the Golden Age of the Jurassic Era, when ferocious lizards roamed the land. Thus use of the expression refers to anything that is big and bad, or totally bad-ass. Use of the word furthers the quest to win Alex $5 out of Zach's pocket for spreading a word.

The act of getting extremely wired on cocaine or crack to the point where your arms assume the T-rex position and your jaw moves furiously as if chomping.
