Money one carries in a conspicuous place to give to muggers when they traverse a dangerous neighborhood. This money stands in contrast to the shoe money, bra money, and crotch money - all wads of cash stuffed in the aforementioned location and totalling a greater amount than the mug money, which is already counted as forfeited.
