This sound comes from Team Fortress 2, Valve’s team-based multiplayer shooter released in 2007. Players usually associate it with the Demoman’s grenade launcher, one of the game’s most recognizable projectile weapons. Short weapon sounds from TF2 spread widely through gameplay montages, meme edits and class-based compilations on video platforms over the years. This particular firing clip stays useful because it is brief, readable and instantly tied to TF2 for players who know the game.
