n. (context slang English) a homosexual
Wikipedia
The pink triangle was one of the Nazi concentration camp badges, used to identify male prisoners who were sent there because of their homosexuality. Every prisoner had to wear a downward-pointing triangle on their jacket, the colour of which was to categorise them by "kind". Other colors identified Jewish people (two triangles superimposed as a yellow star), political prisoners, Jehovah's Witnesses, "anti-social" prisoners, and others the Nazis deemed undesirable. Pink and yellow triangles could be combined if a prisoner was deemed to be gay and Jewish.
Originally intended as a badge of shame, the pink triangle (often inverted from its Nazi usage) has been reclaimed as an international symbol of gay pride and the gay rights movement, and is second in popularity only to the rainbow flag.
"Pink Triangle" is a song by American rock band Weezer. As the third single from the band's second album Pinkerton, it was released to radio on May 20, 1997.
Pink Triangle Products Ltd was a British audio manufacturer specialising in high end turntables.
It was founded in London in 1979 by Neal Jackson and Arthur Khoubesserian. Jackson chose the name 'Pink Triangle' after the symbol used to identify homosexuals in Nazi concentration camps (both Jackson and Khoubesserian are gay).
Initial manufacturing took place on an industrial estate in Maidstone Road, Sidcup, Kent, and later at Lomond Grove, Camberwell, London. The company closed in 2003.
