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.
