Team Fortress 2 is Valve's team-based multiplayer shooter, released in 2007, and the Demoman is one of its nine playable classes, a Scottish explosives expert who can trade his stickybomb launcher for a shield. With that shield equipped, he can launch into a short, high-speed charge, and the accompanying rush has become a familiar cue in gameplay clips, highlight reels and meme edits. It spread through TF2 videos and soundboards because fans recognised it instantly, and it remains useful today as a shorthand for reckless momentum, even for viewers who have never played the game.
