The line comes from Counter-Strike 1.6, released in 2003 as the definitive version of Valve's team shooter, where round outcomes were announced with short radio-style voice lines. It belongs to the same set of commands as bomb has been planted and enemy spotted, all delivered in the same clipped, military tone. As CS clips spread through forums, YouTube and meme edits, the announcement outlived the game itself, becoming a universal shorthand for a team victory that creators still reuse in modern shooters and ironic win compilations.
