What does willy mean?
In British English, willy is an informal, euphemistic noun for the penis. The word has a childlike quality and is often associated with a child’s naming of the body part, although adults also use it jocularly or to soften a reference to sex. It can sound more discreet than the clinical term penis while remaining less crude than some vulgar synonyms. The spelling is chiefly British, though it is understood in other English-speaking countries. In writing, the choice depends on tone: willy may suit nursery speech, comedy, quotation, or an informal account, but formal prose normally uses penis. The word’s history reflects a familiar English pattern: personal names such as Will and Willie were used for the body part by children, helping create a mild euphemism without the clinical or obscene force of other terms.

Etymology of willy
The noun willy is recorded from the early nineteenth century and is generally linked to the familiar form Will, a diminutive of William. The name Will had itself been used as a child’s term for the penis, so willy developed as a mild euphemistic extension. The underlying given name belongs to the English form of the Latinized Germanic name Wilhelmus.
