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.
