This sound comes from the Metal Gear Solid game franchise, where a game over cue marks mission failure. Short clips of it spread through gaming edits, reaction videos, and meme compilations because the meaning is instantly clear even to casual players. It remains popular as a compact failure punchline, especially in stealth game jokes and sudden reversal edits. Fans also pair it with the Metal Gear Solid Alert sound when showing the moment just before everything goes wrong.
