#2 Matt: This chick really wants to hook up with me tonight.
Me: I dont know man, she seems pretty sketch balls to me.

Sketch Ball
Serves as a multiplier of sorts for the adjective "Sketch." Can be used to describe any person or situation that is unpleasantly odd or out of place. Often used specifically to denote a person who may seem untrustworthy, paranoid, or generally displeasing.
"Sitting in a parking lot with your lights off at 2 a.m. is way sketch ball."
