The line comes from Overwatch, Blizzard's team-based hero shooter first released in 2016, where it is the activation call for McCree's Deadeye ultimate ability. As McCree, later renamed Cole Cassidy, locks onto enemies, the drawled warning tells both teams that a devastating shot is coming. Players clipped the clean voice line for soundboards and montages, and it soon spread beyond the game into memes, edits and reaction videos. Its Western swagger and instantly recognisable timing keep it useful long after its original in-game moment.
