This an an act in which a male or female, whilst having a shit in the toilet, then decides to have a wank. This, therefore, bring us to the word shank. A shit and a wank at the same time.
When on holiday with friends, i walked in on my friend having a shit but his cock was in his hands and he was jerking profusely, at which point i said, "aww, man stop shanking, this is our bathroom aswell"
