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.
"Dude, she asked if i poopjasterblevomulate"
"WHAT? what did you say?"
"I couldn't say anything. I just reflex T-rexed until she left"

Females who think they are Muscle Mommy's... But only work Glutes and legs/are built like a T-rex... All Ass a stomach that pokes out and chest/arms of a 10 year old boy(sometimes has lunch Lady arms)and they lean Forward to further define the ass that's barley there
Oh Lord.... There she goes again flexing like a muscle Mommy ... But with all due respect she is built like a T-rex Tommy... Denial is a hard thing to come to terms with

After working out your biceps the following day your arms become sore and unbendable causing this condition. Also referred to as "Dino Arms".
I'm having major issues getting my shirt on this morning. I have a bad case of t-rex arms after that crazy workout.

When laying in bed with someone, facing one another, it is the awkward positioning of one's interior arm (resembling the arm of a T-Rex) which often prevents two people from getting as close as possible.
