The sting comes from Konami's Metal Gear stealth series, where a sharp alert tone plays the instant a guard spots the player, and it became iconic with Metal Gear Solid in 1998. Clips of the sound spread through early gaming montages and Let's Play videos, then jumped to mainstream meme edits and short-form platforms. Today creators pair it in edits with the classic suspense sting and crisp notification-style alerts, because few sounds say 'you have been spotted' faster than this one.
