This sound is widely recognised from the Counter-Strike series, where a flashbang grenade blinds nearby players and briefly overwhelms both vision and hearing. Variations of the effect are known across older Counter-Strike versions and newer clips tagged with cs2 flashbang sound. It spread beyond gameplay because the audio alone clearly communicates instant disorientation, so editors use it in montage parodies, reaction videos and meme formats whenever a scene needs a sudden stunned or overloaded feeling.
