Safeword

A safeword makes it possible for a submissive involved in BDSM to say "No" or "Stop" and pretend as much as he or she wants without really meaning it while still having a safe way of indicating they seriously need the scene to stop.

I am not involved in the BDSM scene but have for completely different reasons negotiated a safeword or a code word with someone. The agreed upon word is "Orange" and is to be used when either of us wishes a certain behaviour to cease or all communication to stop immediately until the following day. 

As I am a forgetful person, I am posting it here for future reference so I can find it when I need it. Otherwise I may end up shouting "Indigo", "Crimson", "Aquamarine" or something else in a futile attempt to bring an end to something.
