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!

SEDIFY

The opposite of DIY.
Somebody Else Does It For You

Friend 1: Hey man, let's start a DIY punk band!
Friend 2: I know you man, you're too lazy to DIY. Why don't you just get signed and let SEDIFY?

"Hmm...I could make my car repair a DIY project...or I could just rely on SEDIFY and take it to the mechanic."
