Top Definition
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.

A vagina that seems bad-ass but in actuality, it just scavenges for sloppy seconds.
I was so drunk I almost got devoured by a vagina-saurus-rex. Thankfully, she was distracted by the guy twitching in the corner.

An enormous cunt.
(Re Jose Mourinho) There's no escaping the fact the man is a very good football manager. Equally, however, there's no escaping the fact he is one of the biggest cunts ever to walk the face of the earth, and I include the Vaginasaurus Rex in that.

1.When someone, male or female, is being an incredible whiny bitch and/or seems like they have so much sand in their vagina;real or presumed, that the Mojave Desert then seems like a sand box.

Their mating call is a sound that comes deep within your throat, is loud; above 80 decibels and you have to wag your tongue back and forth in your mouth to create said noise. Since their nature is to wade in their own self pity, instead of being turned on they reply with "What's wrong with you?" or "You're so fucking gay". And then walk away to go and touch his/herself.

Matt: "Oh whoa is me, my life sucks, I'm going to go and drink all day because no one likes me. I hate my job and I just want to kill myself."

Greg: "Dude, you're such a Vaginasaurus Rex"
