FlyUS is the fictional airline that appears in Grand Theft Auto V, released in 2013, as part of the game's long-running satire of American consumer culture. Its advertising presents an exaggeratedly cheerful, low-cost carrier, and the most shared version ends with the blunt instruction to sit back, relax and shut up. The clip spread through GTA fan pages and soundboards, where players recognised it from in-game radio and television advertising. It has stayed popular because the joke needs no context, travels well in short edits, and instantly signals a fake, overconfident airline.
