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.
Cindy was being such a vaginosaurus rex because she didn't want to go outlike the rest of us.
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
12 step recovery jargon referring to someone new who talks about how great life is, now that they'resober. Usually meaning that the person is out of touch with reality.
