This sound is widely recognized from Among Us, the social deduction game that became hugely popular online in 2020 through streams, clips, and memes. Short audio cues tied to impostor actions spread quickly because they were easy to drop into edits about lying, sabotage, and surprise attacks. The impostor slice sound still shows up in gaming compilations and reaction memes because it instantly signals a backstab or sneaky reveal. It is often used alongside other familiar gaming meme sounds such as Roblox oof or FNAF Jumpscare Scream.
