Original entry ↗
noun

A highwayman's club, billy club. · A slubbing or roving machine. · A tin with a swing handle used to boil tea over an open fire; a billycan; a billypot. · A bong for smoking marijuana.

Selected source glosses provide context, not a complete modern definition inventory

Uncertain, but probably extracted from Scots billypot (“a type of cooking pot”), perhaps originally from the name Billy, a diminutive of William. The condom sense from the E-Rotic song Willy, Use a Billy... Boy, referring in turn to Billy Boy, a German brand of condoms.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
