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.

Rex

An amazing, supportive friend. The best listener, an incredible person. He’s great at finding the silver lining. If you don’t have a Rex, you’re missing out. He’s the absolute best person. He knows how to cheer you up when you’re feeling down. He is funny, kind, and caring. Rex is a badass.

Rex is quite possibly my favorite person in the entire world.

Rex

A very greedy, selfish brat. He is a hypocrite and likes to beg for money. He makes up excuses for why he does not have money. He always wants you to buy stuff for him or asks you how much you have every day. He is a sad person with no life.

Some kid keeps asking me how much money I have!
It was probably Rex.

Dorkatorus rex

A person that is such a dork that they think hatchbacks are cool and they brag about their Excel skills, and they are as clumsy and lumbering as a Tyrannosaurus rex.

My boyfriend is a dorkatorus rex, but for some reason I keep dating him anyway.
