T-Rex dick

When a really big guy has a large cock, but it looks small due to his over-all size, much like T-Rex's arms.

My cock is seven inches, but I'm 6'7", so it looks kinda dinky. I have a T-Rex dick.

T-Rex Defense

If an awkward girl won't leave you alone, make like Ian Malcolm and stop whatever conversation you were having to freeze like a statue. Her vision is based on movement and she will pass you by for tastier prey, like a T-Rex.

"Kelly from the bar came up to me last night and I couldn't shake her off, I had to utilize the T-Rex Defense in hopes she would move on and attack some lawyer guy on a toilet."

Doylum T-rex

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.

I was a doylum T-rex last night, it was so good

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.

"After I played we had a truly trex moment in which he held my hand for 45 seconds and I looked into his beedy black eyes and felt all the emotion flow from me"

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."
