[US]Milner & Milner Black Players 35: It is something of a mystery how ‘mackerel’ ever became associated with pimps.

One informant even told a joke about how a man’s wife was stolen by a pimp, and the man was delayed in discovering his loss by a few mackerel the pimp had left in the wife’s place. A similar story tells of the blind man who, in passing by a fish market, tipped his hat and said, ‘Good evening, ladies.’ [...] It seems likely that the term originated from the French maquereau, a pimp. Probably the evolution of this term occurred in New Orleans, one of the origin cities of Black pimping in America, where French language influences remain strong.
