This sound comes from Counter-Strike, where it plays at the end of a round when the planted bomb is successfully defused and the Counter-Terrorist team wins. Variants of the line are best known from Counter-Strike 1.6, Source and Global Offensive, making it a long-running part of the series. Online, it spread beyond gameplay into memes, compilations and edit culture because the phrase instantly communicates a tense objective being saved at the last moment. Its meaning is so clear that even short clips can use it as a punchline.
