This sound comes from Among Us, the social deduction game by Innersloth that became massively popular online in 2020 through streaming, YouTube compilations and short-form memes. The kill cue is tied to the impostor attack animation, so it quickly became shorthand for betrayal, sabotage and getting taken out without warning. It is still widely used because even a very short clip instantly tells viewers what happened. It is closely associated with the Among Us Emergency Meeting sound in meme edits built around accusation and survival.
