Handkerchief code
BDSM practicioners or casual sex seekers sometimes indicate whether they are a top or bottom, and what kind of sex they are looking for, by color-coded handkerchiefs, worn on the left side of the body for tops and the right for bottoms.
Unfortunately, there is no universally understood color code. People generally agree upon the more common practices, but there is no consensus on the more uncommon techniques.
