Bandanas were used to denote a gay man's sexual preferences.
True Or False: TRUE
A "hanky code" once was used by gay communities to signify sexual preferences, although it differed from community to community. The practice is thought to have gotten its origins from San Francisco gold miners, who took part in square dances with a vast shortage of women. Thus, the man with a red bandana would dance the female part and the blue bandana would dance the male part. It's purported the "mdoern" hanky code was started in the '70s in New York City.
