How to Sign "Joker"
To sign 'joker,' start by forming both hands into 'X' handshapes. Do this by curling your index fingers while keeping your other fingers closed into a fist. Hold your non-dominant hand in front of your chest as a stationary base. Bring your dominant hand just above it, and playfully tap or brush your dominant 'X' hand against the top of your non-dominant 'X' hand. This core motion is the sign for 'joke' or 'kidding,' which is often used contextually to describe a joker.
