A john (U.S.) or a punter (U.K.) is a male client of a prostitute, particularly in the case of street prostitution. Although these are slang terms, they are used by both prostitutes and police in their respective countries. Johns from the United States prefer to call themselves "'mongers", short for whoremonger, a word that has expanded from its meaning of a pimp or bawd, who dealt in whores as a fishmonger deals in fish, to include anyone keeping the company of whores..
