jackwhack 

Part jackoff and part whackoff.

Anyone that is being a jackoff that is doing something the equivalent of whacking off.

There's a guy in a tiger outfit drinking coffee and reading. We sit next to him and I look at him and say "grrrrrr".
He looks back with a blank stare like he has no idea what I'm talking about, then he realizes he's dressed like a tiger, and takes off his tiger ears and goes back to reading.

That guy was such a "jackwhack"

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.
