In British usage, "bagman" is a term for a traveling salesman, first known from 1808.
[1] In Australian usage, it can mean a tramp or homeless man.
This usage has led to an expansion of meaning to include those who solicit bribes for public officials.
When acting as an intermediary in such activities, a bagman may also be called a delivery boy or running man, and may receive a fraction of the money collected.
[9] In criminal operations involving disbursements of cash as illegal payments for some service, a bagman delivers the money, often cash, to the recipient, such as Fred LaRue in the Watergate scandal.
