A nickname for the biggest whore
one knows. Just like Tyrannosaurus
rex means "King of the terrible lizards", Skankasaurus
rex means "Queen of the skanky-ass sluts".
Guy 1:
Dude, I think I can get an easy fuck from Tanya at the
party...
Guy 2: Man, for your own good, stay away from her infested ass! She's such a Skankasaurus
rex!
