Get the Jackshaft mug.
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.

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.
