A fob is a vest pocket in a gentleman's outfit. Often a fob held a pocket watch which was swung from a chain, attached to the vest pocket on the opposite side of the vest. These fob chains often had small pendants - as seals - and these pendants themselves became known as fobs. The word fob is often used for all small pendant-like ornaments which can be suspended from a fob chain.
