The word **阿飞** (ā fēi) is formed through a combination of the familiar prefix **阿** (ā), commonly used in nicknames or informal address, and the character **飞** (fēi), meaning "to fly." It originated as mid-20th century urban slang, particularly in Shanghai, to metaphorically describe a flashy, rebellious young man—someone who "flies" outside the bounds of social convention, often characterized by unconventional Western-style clothing and delinquent behavior. Thus, the term creatively blends informal address with a metaphorical action to coin a vivid social label.
