The persecution of gays in the first half of the twentieth century was so severe that gay people developed their own way of talking, a kind of secret code that amounted to an English dialect, which is known as Polari (from the Italian 'parlare' to talk). Polari declined in usage in the early 1960s, mainly due to the decriminalization and relative acceptance of homosexuality in the United Kingdom. As gays attain greater acceptance, the need for a gay subculture and language diminishes. It's an unfortunate, but long-awaited trade-off for freedom.
Putting on the Dish is video short by London filmmakers Brian Fairbairn and Karl Eccleston, which shows two gay men having a conversation on a park bench, entirely in Polari. First, watch the film to see how much you understand. Then look at the translation below. I understood about 25 percent of what was happening, primarily from context.

The one on the right is rightfully disgusted by this revelation and
