A large covering of skin, referred to as a monstrous foreskin, over a donkeys penis. Usually utilized as an insult from a father to son upon first sight or greeting.
Son *enters house*
Father: “Hello whassack, you got your first fishy finger yet?”
Son: “No you dodgey bastard!”
Father: “One day.”
Son: “Piss off.”
Lancashire dialect word, only ever used light-heartedly as a very mild insult. Pronounced 'wazzock' rather than with an 's' sound. Once famously appeared on a hit record by Tony Capstick, giving it a brief period of popularity with schoolkids, including me, but now only uttered without a degree of irony by coffin dodgers.
