Team Fortress 2, Valve's team-based shooter, made its Sniper class famous for long-range eliminations in modes like Capture the Intelligence, where a single well-placed shot can turn a round. Clips of that rifle crack spread through gaming videos, montages and soundboards as a shorthand for a clean, distant kill, much like other shooter sounds such as a pump shotgun blast or an enemy spotted callout. It remains popular because it is instantly readable, short and dramatic, even for viewers who have never played the game.
