The kill confirmation chime comes from Overwatch, Blizzard's hero shooter released in 2016, where a sharp audio cue fires every time a player secures an elimination. As the game became one of the defining FPS titles of its era, its sound effects escaped the game itself, circulating through frag montages, stream highlights and meme soundboards. The Korean label on this upload reflects how widely the cue travelled across gaming communities worldwide. Today editors use it as shorthand for any decisive win, inside Overwatch or far beyond it.
