Counter-Strike is a long-running team-based first-person shooter where players communicate quickly during rounds, and short radio-style lines like this thank you became part of its in-game language. As gameplay clips, streams and memes spread online, the line was lifted onto soundboards where it could be replayed outside a match. Its brevity is part of its appeal: it is instantly recognisable to players, easy to drop into edits, and still works as a simple polite reaction for viewers who have never played the game.
