Purple Hanky

In the gay hanky code, a purple handkerchief traditionally signals an interest in piercing play, meaning erotic body piercing as part of sexual activity. As with all flagging, placement indicates role: worn in the left pocket it signals a top or piercer preference, and worn in the right pocket a bottom or piercee preference. The hanky code, also called flagging, emerged in 1970s gay leather and cruising culture as a discreet, wordless way to communicate specific sexual interests through the color and position of a bandana. Piercing play, like other kink, is practiced between consenting adults with attention to hygiene, safety, and aftercare. Color meanings varied by city and era, so the code was always a starting point for conversation rather than a fixed rulebook.
