t-rex t-rex

An expression reminiscent of the Golden Age of the Jurassic Era, when ferocious lizards roamed the land. Thus use of the expression refers to anything that is big and bad, or totally bad-ass. Use of the word furthers the quest to win Alex $5 out of Zach's pocket for spreading a word.

T-rex t-rex! T-rex is a hungry mother fucker!

Octavious Rex

A minorly famous character that made a couple second appearance on Spongebob Squarepants.

My favorite part of the episode is when Octavious Rex goes 'Meep!'.

Gaseous Rex

Someone whose farts are so foul and lethal, they can kill more people than a raging T-Rex.

Oh no, Gaseous Rex just had Mexican food for lunch. Better get outta here before we get a whiff of his lethal stench!

Skankasaurus rex

A nickname for the biggest whore one knows. Just like Tyrannosaurus rex means "King of the terrible lizards", Skankasaurus rex means "Queen of the skanky-ass sluts".

Guy 1: Dude, I think I can get an easy fuck from Tanya at the party...
Guy 2: Man, for your own good, stay away from her infested ass! She's such a Skankasaurus rex!

Gruntosaurus Rex

taking a dinosaur-sized crap; would win the "shit of the year" contest; the kind of dump where you lose weight.

After not crapping for a week, I sat down and loaded up the bowl with a Gruntosaurus Rex.

The plebasaurus Rex would go hungry for another day as he was broke
