orange hanky
What does orange hanky mean?
In the gay leather hanky code, orange is the wildcard. It doesn't lock you into one kink — it broadcasts that you're open, adventurous, and down to negotiate just about anything. Worn back left pocket = you take the lead; back right = you receive. The code itself started in the 1970s so men could cruise each other in bars without saying a word out loud, back when saying it out loud was dangerous.
Origin
Part of the gay handkerchief/bandana 'hanky code' that took hold in 1970s US leather and cruising culture; left pocket signals top/active, right signals bottom/receptive.
