The alert sound comes from Metal Gear Solid, Konami's stealth game series in which guards raise the alarm with a distinctive electronic sting and an exclamation mark when they spot Snake. The cue became shorthand for being discovered, first among players and later in online videos, where editors reused it far beyond gameplay. Bass-boosted versions spread as memes because the louder, distorted mix exaggerates the original warning, making an ordinary catch feel like a major event. That shared recognition keeps the sound useful in short edits today.
