Team Fortress 2 launched in 2007 as Valve's class based multiplayer shooter, and its domination system tracks when one player kills the same opponent repeatedly without dying to them. Reaching that status triggers this sting and marks the victim as dominated until they get revenge. Clips and edits from TF2 spread across YouTube and gaming forums in the following years, and the sound became shorthand outside the game for owning another player. It remains popular because the domination mechanic is so specific and the sting is instantly readable.
