This sound comes from Valorant, Riot Games' tactical shooter released in 2020, and is tied to Raze's ultimate ability warning line. Players know it as one of the most recognizable danger cues in the game because it signals an incoming explosive attack with almost no time to relax. The clip spread beyond normal gameplay through highlights, livestream edits, and short-form memes, where it is used as a dramatic alert in much the same way as enemy spotted or a danger alarm sound effect meme.
