Shelbasaur 

A special branch of dinosaur that lived approximately 230 million years ago , and became the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic (about 200 million years ago) until the end of the Cretaceous (65.5 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic era.

Many people might think that all dinosaurs have became extinct but shockingly this one breed of dinosaurs lived, no one knows why and scientist are still trying to run test.

If you ever run into one of these dinosaurs theres only 2 things you can do:
1. Run
2. Pray

These dinosaurs are VERY territorial and VERY aggressive.

NOTE: They also tend to breathe fire, Mostly the females ( No one knows why, It just happens. )
Slidoo is primarily used as the example for the Shelbasaur due to the fact that she is the last of her kind.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
