Safe word
A safe word is an agreed signal that immediately pauses or stops play, letting partners explore intensely while keeping a reliable brake.

A safe word is a pre-agreed word or signal that instantly pauses or stops an encounter, no questions asked. It gives everyone a dependable brake, which paradoxically makes it possible to relax and explore more freely.
A common system is the traffic-light model: red to stop, yellow to slow down or check in, green to continue. The key is choosing something unlikely to come up naturally, so it is never ambiguous in the moment.
Safe words matter most where ordinary words might be part of role-play, but the principle belongs everywhere: a clear, respected signal to stop. When someone uses it, play halts immediately and care takes over.
