Team Fortress 2 launched in 2007 as Valve's class based multiplayer shooter, and the Medic is its dedicated healer, a German doctor whose job is keeping teammates alive under fire. Players trigger the call constantly in matches, so the shout became shorthand for needing help inside the community. Clips and soundboards later carried it into edits and streams outside the game, where it now signals low health, panic or a badly timed injury even to viewers who have never played a match themselves in public lobbies today.
