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.

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.
