A stupid whore who thinks she is hott shit but in reality resembles a t-rex or raptor or dinosauric looking creature.

Might be good at giving head because her looks are getting her no where.

Has no friends becuase everyone knows she is a slut.

She thinks she owns everyone and everything but all she really has is herpes.

A woman behaving in a cunt-like manner that has a giant jagged stick up her ass; thus, the stick amplifies her "cunty" behavior due to the soreness it causes (i.e. cunty-sore-ass)

Surprisingly these particular cunts are not as rare as you may think and there is a strong correlation with the amount of typical cunts in one's town, city, community etc.
"WTF that same bitch from yesterday purposely didn't move and proceeded to block the doorway so I couldn't get on the train" "Damn Joe looks like that cuntasaurus struck again!"
