Can mean one of two things:

1) To stroke a penis, either by masturbation or by doing it for someone else
2) To kill someone in Maphia lingo
For definition 1: "I'm whacking off right now.", "Your sister whacked me off last night."

For definition 2: "If I find out Lenny's wearing a wire, you're gonna whack him off.", "I'm going to whack you off if you don't whack off Lenny."
