Vaginasaurus Rex 

A pejorative term I developed in reference to some, heartless, destructive, and vindictive women. From "vagina", referring to the mammalian birth canal and "dinosauria" (coined by Dr. Richard Owen) meaning "fearfully great lizard." The term is meant to convey the epitome of "bitch" potential that some (emphasized) women display.

My friend's ex-girlfriend broke up with him the day after her car fell off the ramps and crushed his legs while he was changing the oil. Now she's dating his mom. What a Vaginasaurus Rex.

Moni-rex-asaurus 

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?"

Sex T-Rex 

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!

T-Rex 

A rare species of dinosaur that lurks flamboyantly on piano benches.

T-rex hand 

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.

"Man, that girl was all up on me and then I saw the T-rex hand and I had to get the fuck out."
