Polari

Polari (from Italian parlare 'to talk') is a form of slang or cant used in Britain by some actors, circus and fairground showmen, professional wrestlers, merchant navy sailors, criminals, sex workers, and, particularly, the gay subculture. There is some debate about its origins, but it can be traced to at least the 19th century and possibly as early as the 16th century. There is a long-standing connection with Punch and Judy street puppet performers, who traditionally used Polari to converse.
