The T-REX

something that is done where both arms are bent upwards to the face to show the appearance of short arms; most people experience this around weirdos or during sex.

I accidentally did the T-Rex last night when i was with Sandra.

T Rex Arms

Physically weak individual, a person who wouldn’t be able to carry you if you got shot in a firefight.

You looked like T Rex Arms out there when you attempted over and over to buddy carry that guy.

T-rex

When you are so drunk that your knees fall into to the teepee position (imagine a giraffe trying to drink water spastically). Your arms then tuck into your body and you assume the T-Rex position as you gobble along on the dance floor.

I think I just saw a dinosaur on the dance floor... the bloke must be in T-Rex mode
