The line comes from Valve's Counter-Strike series, where planting the C4 is the central objective in bomb defusal matches and the announcement warns Counter-Terrorists to retake or defuse. It carried over from earlier versions into Counter-Strike: Global Offensive in 2012 and Counter-Strike 2 in 2023, keeping the same clear announcer style. Outside matches, players clipped and shared the phrase as a shorthand for a timed threat, and it spread through gaming montages, streams and meme edits where a calm warning makes a situation funnier.
