Handkerchief code

The handkerchief code (also known as the hanky code, the bandana code, and flagging) is a color-coded system, employed usually among the gay male casual-sex seekers or BDSM practitioners in the United States, Canada, Australia and Europe, to indicate preferred sexual fetishes, what kind of sex they are seeking, and whether they are a top/dominant or bottom/submissive.

Wearing a handkerchief on the left side of the body typically indicates one is a "top" (one considered active in the practice of the fetish indicated by the color of the handkerchief), while wearing it on the right side of the body would indicate one is a "bottom" (one considered passive in the practice of the fetish indicated by the color of the handkerchief). The hanky code was widely used in the 1970s by gay and bisexual men.

The wearing of various colored bandanas around the neck was common in the mid- and late-nineteenth century among cowboys, steam railroad engineers, and miners in the Western United States. It is thought that the wearing of bandanas by gay men originated in San Francisco after the Gold Rush, when, because of a shortage of women, men dancing with each other in square dances developed a code wherein the man wearing the blue bandana took the male part in the square dance, and the man wearing the red bandana took the female part (these bandanas were usually worn around the arm or hanging from the belt or in the back pocket of one's jeans). It is thought that the modern hanky code started in New York City in late 1970 or early 1971 when a journalist for the Village Voice joked that instead of simply wearing keys to indicate whether someone was a "top" or a "bottom", it would be more efficient to subtly announce their particular sexual focus by wearing different colored hankies.
