A cheap ass. The person, who at dinner in a restaraunt when its tip time, whos arms seem to be too short to reach into their wallet and tip their fair share. T rexes, frequently seen reusing napkins and relying heavily on the "if its yellow, let it mellow" flushing principal, are the utmost cheapest, tight waded, penny pinching bastards around.
Frank: "Steve, how much did you tip?"

Steve: "I dont believe in tipping... *leaves table*"

Frank: "You god damn t rex... *shells out more cash*"

Get the t rex mug.
When you get so drunk that you become retarded and you tuck you elbows into your side and still try to use you hands, but they are short and useless, just like a T-Rex. This state of drunkeness my also be accompanied by slurred yelling that sounds like a roar. Getting this drunk usually involves blacking out and falling down.
Keven got so drunk last night he started T-Rexing.
