Pregnasaurus 

A large lumbering animal with an extended stomach and a lifespan of about nine months. Animal is prone to ligament pain, especially as it reaches maturity. Know for uncontrollable mood swings, strange eating habits, and a cooing noise made when near children's clothing.

The pack of pregnasaurus waddled into the baby section of the department store and began making strange cooing noises. Spectators were amazed by the gentle nature of the pregnasaurus until one became ferocious with hunger and proceeded to hunt and devour a candy bar.

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.
