Among Us was released by Innersloth in 2018, and the Guardian Angel was added as a role for dead crewmates in the November 2021 roles update. Unlike other ghosts, a Guardian Angel can cast a temporary protective shield around a living player, blocking an Impostor kill attempt and producing this blocking sound. As clips of clutch saves were shared from streams and lobbies, the effect became shorthand online for an unseen protector intervening at the last moment, which is why editors still reuse it outside the game.
