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.

Penisaurus rex 

A beast with the world's largest 5 inch penis. It should be noted that the 5 inches is in reference to the radius of the penis. When erect, it can extend up to 15 kilometers in length.

The word "Penis-" is the latin word for "Tail" and the term "rex" is also from the latin word "king". Hence "Penis King"

Penisaurus rex is often abbreviated to P-Rex. The P-Rex is often synonymous with the word AVBP.

The most common prey for the Penisaurus rex is the Danfag

In some cultures, the P-Rex is referred to as "Moosa, the beast with the 2.5 ton AVBP". It sometimes suffers from back problems.

The Penisaurus rex used its AVBP to crush the Danfag

Johnny is the Penisaurus rex.

Occasionally, the Penisaurus rex would suffer from Penisclerosis and would get a 28 hour erection.

When the P-Rex caught a case of Penisclerosis, it used its AVBP to smack Danfags across the face.

People worship the Penisaurus rex by repeatedly chanting "Moosa-Bhai!! Moosa-Bhai!!"
