the secret hand signal that means "lets bail"

so we have this thing where if one of us isnt feeling it for whatever reason at a meet or a club, we do this little signal where we tap our left wrist like we're checking a watch (even tho neither of us wear watches anymore lol). that means "im ready to head off whenever you are". no judgement, no need to explain, no awkward convo in front of others. just tap the wrist and the other one starts making excuses about an early start in the morning. saved so many nights from ending badly. anyone else got a "let's bail" signal w your partner?
