When you're fucking that bare muff and you become so pleasured that you lose the capability of your arms and you become a paraplegic. This makes your arms resemble a T-rex's arms.

A term to define an short girl with a large ass, pig nose and short, stubby arms. She runs like a raptor, and when she stops moving the smell of ass moves in for it's silent but deadly kill. This girl will also have a large, large, gianormous vagina. It will be so large/loose that when you stick 3 fingers to a fist insider her vagina and she will not even know it is there.
Boy: "OMG, Look at that girl with the big ass, short stubby arms, and the pig nose that runs like a raptor."
Girl: "That's a Moni-rex-asaurus"
Boy: "Do you smell ass?"
Girl: "That's a Moni-rex-asaurus"

A person who wants to have sex all day long. They are either thinking about it. Working toward getting it or having it at almost all times!
I was rubbing Alicia's shoulders...next thing you know I've got my pants off getting a smoker! That girl is a sex t-rex, we fucked all night!
It wasn't until the next morning I realized how many miles of cock had already beat that moose knuckle into submission!

A serverely deformed hand and wrist which in turn resembles that of a tyrannosaurus rex. There cannot be more than three fingers and one thumb. It is most deadly when the host is an otherwise hot chick. Beware.
