Knob the builder

Place your knob inside a vice, make small but painful paper cuts along the head.
Douse salt water all over it whilst twisting the vice making it tighter.

boat knob

Similar to a turtle head, a boat knob is a small piece of poo, that has emerged from the anus, while the rest of said poo is still submerged inside the rectum.

Bogan 1: Oi where's the dunny cunt I got a boat knob hangin out.
Bogan 2: Down the hall and to the right you filthy cunt.
