Jackshitting

Genuinely doing "jack shit" all day. "Jackshitting" is often referred to as "procrastinating", but procrastinating implies you actually have something to do, while you jackshit without having to have a life.

Susie: "James you wanna go paint drying?"
James: "Nah, I'm okay. I think I'll just jackshit here on the couch."
Susie: *sigh* "You're always jackshitting about."

Jackshaft

A. The act of masturbating a thick meaty phallus, roughly and with intent (typically to completion). All twig action, the berries don’t get a look in.

B. A good band name.

A. Fancy popping around this evening for a drink? Only if I’m also gonna get a good old jackshaft - I’m backed up at the moment, and suspect I have a hair trigger.

B. Hey guys - I’m heading down the club tonight, a few pints and to watch that band Jackshaft - they’re awesome, and with a hot singer.
