The sound is based on the flashbang grenade effect from Counter-Strike: Global Offensive, the long-running tactical shooter released by Valve in 2012. Its blast-and-ring audio became a familiar shorthand in shooter culture, then spread into meme edits on YouTube, TikTok and Discord. People use it because the effect is instantly readable even without gameplay: it signals being stunned, overwhelmed or caught off guard. It is often used alongside other FPS cues such as a hitmarker to make short clips feel more like in-game moments.
