Preggersaurus 

A woman using pregnancy as an excuse to be demanding, selfish, rude, lazy, and all around mean. Usually evolves from a bridezilla. Later evolves into an uninvolved mother, expecting people to continue taking care of her child.

Do not engage or encourage these women, instead ignore them and let them carry their chosen burden alone. This may help them realize that it's not your job to take care of them, and that they should ask for help politely if they want/need it.

Wow, ever since Karen got knocked up, she's been a real Preggersaurus.

Can you believe that preggersaurus!? She thinks just because she chose to have a baby she can tell me that I have to clean her house and buy her groceries? Ridiculous!

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.
