As interesting as this discussion is, I can't help but wonder what words people have been using as safewords? Something obvious like "mercy" or "safety", or something totally unrelated like "biscuit"? Or is it a secret? Do you chose a word with special meaning, or just a random word from the dictionary? I know this is all probably up to individual preferences, but I've never actually heard someone say what their safeword is... makes me curious why.
