This sound is widely recognized from Among Us, the social deduction game by Innersloth released in 2018 and popularized worldwide in 2020 through streaming and short-form videos. The impostor kill cue became a meme because it communicates instant betrayal with almost no setup. Online, people pair it with suspicious behavior, prank reveals and dramatic edits. It still shows up in gaming compilations and meme posts because viewers immediately connect it with being caught, betrayed or suddenly removed from the scene.
