According to the book The Meaning of Liff, Wetwang refers to a moist male fiddly bit, although for the sake of the children we will stay with the official explanation. This is that the original name was Wetuuangha derived from the Norse word vaettvangr meaning a place where they heard court cases in a field. There is a river running nearby. Perhaps they caught a fellow skinny-dipping and he was dripping wet when they nicked him for public indecency. The truth is not always as strange as we may think.
