jackpack 

n. The bag in which Jack Bauer carries his gun, PDA, ammo, cell phone, duct tape, knife, scope, etc. It is NOT a man purse.

The terrorists thought they had Bauer at last, but he pulled a bazooka out of his jackpack.

jackwacker 

A person who sucks at life. They are incapable of performing basic and simple daily tasks (with the exception of masturbation).

You have your left turn signal on and are clearly trying to merge into the left lane; instead of slowing down to allow you to change lanes, the Jackwacker behind you speeds up to block your access. This guy is a complete Jackwacker; he sucks at life.
