Polari is an eclectic mix of slang, dialects and foreign words, and original words and phrases, woven into English language grammar and syntax. Even today, you have used Polari if you've ever had a few bevvies at the pub, zhooshed up your bijou flat, or said something is a bit naff.
Before homosexuality was decriminalised, Polari allowed gay people to speak openly and identify themselves as gay without attracting unwanted interest or the attention of undercover charpering omis (policemen). Unless you were in the know, you would only partially understand what was being said and hear nothing incriminating.

Polari started declining after the 1967 Sexual Offences Act made homosexuality legal. Nevertheless, it is a proud part of our LGBT history.
