The line comes from the radio command system in Counter-Strike, a feature dating back to the original game and carried into Counter-Strike: Global Offensive, released by Valve in 2012. Players trigger it to coordinate a fast push onto a bombsite, and its short, repeated phrasing made it one of the most recognisable callouts in the series. Clips of the command later spread beyond matches into gaming montages, streams and meme edits, where it is now used as a universal cue to start moving immediately.
