The clip comes from Destiny, Bungie's long-running online shooter, and features the Drifter, the shady vendor who runs the Gambit mode in Destiny 2. His exaggerated vocal reactions became a familiar part of the game's personality, and players began lifting short lines and sounds for use outside matches. The stretched 'ooh' works especially well as a standalone reaction because it needs no context to be understood. It continues to circulate in gaming edits, streams and meme videos as a quick way to signal mock surprise.
