A short chain or ribbon attached to a pocket watch; a small decorative item attached to a keychain. Also refers to a remote control device for cars or security systems.
Possibly from German 'Fuppe' (pocket) or related to obsolete 'fob' meaning a small pocket in the waistband of trousers. The word appeared in English in the 17th century when pocket watches became fashionable. Modern usage expanded to include any small attached device or ornament.
The humble fob evolved from a practical necessity - pocket watches were expensive and dropping them could be catastrophic, so the decorative chain served a vital protective function. Today's car key fobs continue this tradition of combining utility with status display, as luxury car fobs often feature premium materials and sophisticated designs.
