It's what you promise boyfriend after he gives you a full body massage. Its starts out as really great sex until the mood is killed when you realize the window is wide open and your neighbor has been watching. After closing the window, you resort to finishing him off by hand, but boyfriend has the endurance of a steam engine and you soon become very bored and distracted by the TV show Skins. Without noticing, you become too aggressive, and he eventually makes you stop. Boyfriend will have blue balls in the morning.
Me: Hey babe, want a ZJ?
Boyfriend: Never again.

Extended form of ZJ is Zero Job. The zero refers to zero gravity. In this case a ZJ is when you get a blowjob in space. This is extremely expensive and you probually can't afford it. Important: This blowjob must be done off the ground.
That old rich bastard got a broke hoe and spent a million to go in space and get a ZJ from the slut.

A standard BJ, but instead of swallowing the guy pulls out and makes a "Z" on the girl's face with the cum. The "Z" stands for ZORRO.
ZJ, if you don't kwow what it is, you can't afford it.
