This sound comes from Red Dead Redemption 2, Rockstar Games' western action game released in 2018. Players associate it with the honor system, where Arthur Morgan's actions shift his moral standing up or down. Online, the high honor cue spread in edits, memes, and short clips as an easy way to label a moment as good, selfless, or redeemed. It still gets used because the meaning is immediate even for casual players, and the short sting fits cleanly into reaction-heavy video formats.
