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.

The scariest creature known to man.

I saw this monsterlike creature roaming the plains at a buffet and it made me go blind. I think it was a pregosaurus 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.

Preggosaurus Rex 

A pregnant woman who believes the world revolves around her and the spawn baking in her uterus. These women most likely had large and elaborate weddings with several rules and regulations for the groom, wedding attendants, and the guests (also see Bridezilla or beebee). Attention must be on her at all times. Caution, tantrums will ensue and Armageddon will occur if she does not get what she wants. Women can become one with no warning at any time from conception to birth.

Barbara: You know, Alexis is really becoming a Preggosaurus Rex.

Cindy: Really? Why?

Barbara: Because, that biatch put the Orbit travel system, baby Bellini custom made furniture, and Abercrombi and Fitch Kids on her baby registry. AND she also is throwing her own shower because her sister is fed up and expects us to pay $56 per person at the St. Regis Hotel for the party!

Cindy: Say wwwwuuuuuttt?! I was just going to get her a 3-pack of bibs from Target.

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.
