Pre-Sid Vicious, pre-any stringy young male, "Punk" referred to the passive or "bottom" partner in a male-on-male or femal-on-male prison sexual relationship. (The dominant or "top" man/woman was called the "jock, jocker" or “jockes”) Since the punk was usually the scrawnier and younger of the two, that meaning of the term escaped into the general culture and eventually became attached to young, rebellious men fronting kick-ass rock bands.
