The gift that keeps on giving!
Making love to yourself.

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."

Something extremely large or noisy.
"The car hit him and I heard this whack-off BANG"
"She has whack-off breasts." (This can also link to "whack off" meaning "to masturbate")
