A term used for masturbation when the person masturbating has arthritis in their wrists; this makes a sound referred to as a clank making it a clank wank.
Jack : Did you hear about Daniel and his arthritis?
Charlie : Yeah, he said he had a clank wank yesterday. Everyone in the apartment building could hear it.
Slang for "Head", much like "Noggin" or "Bonce".
Is that a bandage on your Gippler?
Yeah, an unfortunate during my second circumcision. Bashed right in the Bonce.
