Open mid is an informal way for a team to give up before starting a surrender vote. When players choose to open mid, they stop defending the center lane and allow the enemy team to push freely, often after falling far behind during the Early game or losing control of key Objectives.
The phrase appears most often in regions that favor fast matches, where players may decide that continuing to fight offers little chance of recovery. Calling open mid signals that the team no longer plans to contest the map and expects the opponent to finish the game without further resistance.
