Safeword

A safeword is a code word or series of code words that are sometimes used in BDSM for a submissive (or "bottom") to unambiguously communicate their physical or emotional state to a dominant (or "top"), typically when approaching, or crossing, a physical, emotional, or moral boundary. Some safewords are used to stop the scene outright, while others can communicate a willingness to continue, but at a reduced level of intensity. Safewords are usually agreed upon before playing a scene by all participants, and many organized BDSM groups have standard safewords that all members agree to use to avoid confusion at organized play events.
