Scummy Turn On - a chick that is really scummy, but yet you still find yourself attacted to her.

That chick is two steps out of the trailer park but she still has the STO.

a male who enjoys banging lots of skanky, easy women; a male who proactively looks for dirty women to nail

Brad took that nasty chick home last night. He's such a skank pimp.
