SP

Short for the term "Sexual Predator" but typically used more to describe:
1) Adult males that behave overly aggressive towards the opposite sex.
2) Men with creepy appearances that tend to stare at girls much younger than them or act in a creepy manner towards females.
3)Any act of preying on members of the opposite sex in hopes of sexual gratification.

That old creepy guy at the bar is so "SP".

Wow SP!... Are you staring at that chicks ass?

That guy with the video camara at the wet t-shirt contest was "SP".
