👊✋ represents a hand gesture commonly known as "rock-paper-scissors." It involves two players simultaneously forming their hands into one of three shapes: a closed fist (representing rock), an open hand (representing paper), or an extended index and middle finger (representing scissors). The game is played by comparing the chosen hand gestures, with rock beating scissors, scissors beating paper, and paper beating rock. It's a simple yet fun way to make decisions or settle disputes in a playful manner.
