This sound comes from Counter-Strike: Global Offensive, the team-based shooter released by Valve in 2012. The bomb objective mode helped make cues like defusing and bomb has been planted instantly familiar to online players. Short CS:GO sounds spread widely through frag movies, Twitch clips, and meme edits because they communicate pressure in a fraction of a second. The defuse cue still gets reused outside Counter-Strike whenever a creator wants to suggest a risky, time-critical moment.
