Skankasaurus Rex 

A girl who is complete white trash. She is also unattractive, an attention whore, a slut, and any other combination of unbecoming qualities. Generally can be spotted in the local watering hole hitting on old skanky men in order to obtain free drinks.

That girl is such a skankasaurus rex she has sat on four old nasty laps in the past 15 minutes.
