This effect comes from Among Us, the social deduction game developed by Innersloth and originally released in 2018. It is associated with an Impostor kill animation in which a crewmate is stabbed during elimination. The audio became widely recognizable as the game surged in popularity through livestreams, gameplay videos, and memes in 2020. Creators still use it because the compact hit communicates betrayal and defeat immediately. Like the Roblox oof, it also works beyond its original game as shorthand for a character losing or being abruptly removed.
