The game over cue comes from the Metal Gear Solid series, Konami's long-running stealth games in which a failed mission ends with this sombre sting instead of a simple jingle. As clips and playthroughs spread on YouTube and Twitch, editors began lifting the sound to punctuate their own fails, because audiences recognised it instantly even without seeing the game. It has stayed popular as a meme shorthand for defeat, used far beyond Metal Gear itself whenever a plan collapses on camera.
