The perfect woman. A Shasta mcnasty has it all: brains, body, personality, everything a man could want mixed into one amazing lady.

Shasty McNasty 

The act of having crazy sex. One that is horny all the time. Loves to play with Rusty Pipes balls. A person who loves to bite and lick one specific persons balls. Someone who sells crack rocks to Russell Kennedy. A crazy chick.

Shasty McNasty was in my room last night? Have you seen her today?
