Plebosaurus-Rex 

These carnivorous creatures lack friends, and make themselves look really good because they also lack self-esteem. These creatures know that they are Plebs and thus they don't change. They feed on the penises of teachers, being massive arse-kissers. If they get detentions then their lives are over, then contemplate suicide.

Some Plebosaurus-Rexes do commit suicide and even the family members will dance on their overly-wide graves. Life is better this way as scientists like Steven Hawking know their threat on the popularity of others while P-Rexes are in a close proximity. Steven, and millions of others like me, want P-Rexes to be extinct from the planet as they are a large danger to humanity.

Chris: Lol, I just owned him on facebook! Look how popular I am, Imaginary Friend!
Spencer: Don't be a Plebosaurus-Rex, Chris!

Chris: Oh no! A detention! Why!! My life is RUINED!! I'm always licking Mr. Lavender's arse!
Lewis: You're such a Plebosaurus-Rex.

Pedosaurus Rex

A Pedophile of near unreachable levels of pedophilia who like to stalk his or her prey in school changing rooms and playgrounds. They are solitary creatures who hunt alone and seek out unsuspecting children of the neighbourhood.

pregosaurus 

A female of small build, like a bird, but large belly due to infiltration of male seed. Often walks with a waddle late in her term. Easily agitated with the ability to acquire a wide spectrum of moods in a short period of time.

The only creature more dangerous than the T-REX was the pregosaurus.

Pregosaurus Rex 

A pregnant woman who acts as if she is the first person to ever be pregnant. Quick to anger and quick to tears.

I'm going to work late rather than go home and face the wrath of Pregosaurus Rex.
