What does willie mean?
Willie is best known in modern English as an informal, often vulgar noun for the penis. It occurs in casual and humorous speech, particularly in British and American English, and its register is too informal for most formal writing. When capitalized as a name, Willie is a familiar form of William that may express affection, informality, or mild contempt. The word's history begins with the English tradition of forming nicknames from given names: Willie is a diminutive of William, related to forms such as Will and Willy. Its separate anatomical meaning is long established in colloquial usage, although the precise origin and earliest attestation are not certain. As a vocabulary word, Willie is therefore notable both for its humble beginnings as a personal nickname and for the marked contrast between that friendly capitalized usage and the much blunter lowercase meaning.
