When you're sitting on your girlfriends face for a blow job and you have her arms pinned down with your legs, and yell at her to use her hands. The attempt she gives is considered a T-Rex.

When you hug someone from behind while their arms are to their sides. The person being hugged can only move their arms up to their elbows therefore appearing to have short arms like a t-rex.
I like it when my girlfriend roars as I'm t-rexing her.

"Man, Christian was really T-Rexin' last night. He drank 24 shots of peach schnapps. What a retard!"

A physical condition most commonly affecting females of short stature and large bust size. The combination of short arms and enormous breasts leads to the woman's inability to pick up objects without knocking them over with her breasts. So named for similarity to a T rex's inability to beat itself off due to short arms. Condition is exacerbated through alcohol consumption and is most noticeable when beer bottles are knocked over.
Did you see that bizzle at the bar last night spilling everything, she had T rex tits and kept falling over!

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.

The instinctual response to bring one's arms up to ones's chest comically, much like in the manner of a T-Rex. This is done in response to an extremely awkward situation in which one is left speechless and can only resort to reflex t-rexing. This reaction is also applicable to when someone you find particularly obnoxious comes into the the room and you signal to your friends your dislike of said person without giving yourself away.
"Dude, she asked if i poopjasterblevomulate"
"WHAT? what did you say?"
"I couldn't say anything. I just reflex T-rexed until she left"
"WHAT? what did you say?"
"I couldn't say anything. I just reflex T-rexed until she left"
