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!
