A pejorative term I developed in reference to some, heartless and destructive women. From "vagina" referring to the mamalian birth canal and "dinosauria" (conined by Dr. Richard Owen) meaning "fearfully great lizard" The term is meant to convey the epitome of "bitch" potential that some (emphasized) women display.
My friend's ex-girlfriend broke up with him the day after her car fell off the ramps and crushed his legs while he was changing the oil. Now she's dating his mom. What a Vaginasaurus Rex.
When someone is being a real tool, call them a vaginosarus rex. Which basically means you are a dinosaur's vagina. Best used on your aunt who won't go to dinner with you.
When the either one or both of the vagina lips are swollen. mostly likely caused by a yeast infection, a latex allergy, a spermicide allergy, or rough sex while not properly lubricated. Sometimes it can be painful or itch. The best way to deal with it is to always wear liners, avoid super tight clothing as they cause yeast infections, and find out if you have allergies to latex or spermicide. If you have a Vaginasaurous in your pants, it helps to place a small ice pack in your panties to help ease the swelling.
Jane was scared when after sex her vagina was swollen. She asked her best friend what to make of it and she simply said, "Don't worry. You just have a slight case of Vaginasaurous."
