Elbow Rule: A player's elbow must not cross the edge of the table during a throw; Interference: Distracting a player during their throw; Ball Retrieval: Touching opponent's cups when retrieving a ball
Why people argue about this
People often assume that elbowing is just a minor infraction in Beer Pong, thinking it's only about direct contact with their opponents' cups. However, the real issue is actually about blocking or interfering with the ball’s path when an elbow is used to disrupt the flow of play, which can be quite deliberate and intentional.
