The line comes from Overwatch, released by Blizzard in 2016, as the ultimate ability cue for the gunslinger Cassidy, originally named McCree. When players hear it in a match they scatter for cover, knowing his Deadeye will lock on and fire. Clips and parodies spread quickly on YouTube and Twitch, turning the warning into a general western meme for any standoff moment. Like other famous game callouts such as enemy spotted, it remains popular because a few words instantly signal danger, timing, and an unavoidable confrontation about to happen.
