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*"

While someone you know is incapacitated either drunk or just heavily sleeping take rubber cement and apply it to the entire front section of a bare chest and bring the arms up to the chest, hold firmly until the rubber cement dries.

When the unsuspecting victim awakes they will find themslves doing the T-Rex and just as pissed.
John was so drunk last night we T-Rex'd him to get a laugh, you shold have seen his hands flailing around when he woke up, he had no idea what had just happened.
