0 a form of slang used by some groups of people in Britain, especially by gay people and especially in the past:
Polari was adopted by the British gay community and its use was rife in Soho's gay clubs and bars in the 1950s.
Retaining its roots in showmanship, secrecy and dodgy dealings, Polari evolved into a vehicle for campery, bitchiness, filthy jokes and innuendo.
The characters spoke in Polari, a bizarre mixture of the Romany language and homosexual streetcode.
"Bona!" as they say in Polari.
