The cue comes from Konami's Metal Gear Solid series, first released in 1998, where stealth is central and detection changes the whole mission. The sound was designed to give players immediate feedback that they had been seen and needed to hide or fight. Clips of gameplay spread the sound beyond the games, and editors began reusing it in meme videos, streams and compilations. Its link to being spotted remains instantly understood even by people who have never played the series, which keeps it popular for surprise reveals.

The Metal Gear Solid alert sound effect played when a guard spots Snake, now used in videos and memes for sudden discovery and surprise moments.
This is the sharp alert cue from Metal Gear Solid that plays the instant an enemy guard sees Snake. It is a brief, punchy electronic sting paired with the iconic exclamation mark appearing over the guard's head. The sound lasts just under two seconds but cuts through any scene instantly. Viewers recognise it as a moment of being caught red handed, and the sudden shift from quiet stealth to danger creates instant tension and comedy depending on the context of the clip shown.
