This sound comes from League of Legends, Riot Games' long-running multiplayer online battle arena released in 2009. The missing ping became a standard part of in-game communication, especially when warning that an opponent had left vision or lane. Outside the game, creators started using it in clips where someone disappears, misses a cue, or causes avoidable chaos. Its staying power comes from how short and instantly readable it is, much like a discord notification or a simple ding sound effect in comedic edits.
