slam junk

A variation on a handjob, a slam junk is performed by jumping in the air with your arm outstretched, then slamming your hand, masturbation-style, onto the recipient's dick as if dunking a basketball. The more preferable variety of this position is performed with the recipient at a slightly higher elevation of 10 feet, although this is optional.

Yo, man, go lay down up there and I'll give you a slam junk!
