A person who is an absolute whore, and does absolutely anything for cheap sex with everyone. A bit like a tyrannosaurus will hunt down anything and eat it, a tyrannowhoreus sex will hunt down all the man meat it can find just to eat/bone it.
Dude: Hey that girl over there is a Tyrannowhoreus Sex, she sucked half the guys in college!
Dude2: Shit she can't see us if we stand still! :S
