The cue comes from Overwatch, Blizzard's team-based hero shooter released in 2016, where each hero builds charge toward a powerful ultimate ability during a match. When the charge completes, the game plays this short ready sound so the player knows the ability can be used. Clips of the sound spread through gameplay videos, streams and short-form edits, where creators borrowed it as a shorthand for readiness and a big move. It remains popular because Overwatch players recognise it instantly, even outside a match, and because it gives any reveal or comeback a clear, familiar sense of timing.
