GTA Online is the multiplayer mode of Grand Theft Auto V, where players fly jets and helicopters, drive armed vehicles, and use homing missiles against other players. The missile lock warning is one of its in-game audio cues, signalling that an incoming missile has acquired a target and the driver needs to evade or use countermeasures. Clips of chases, dogfights and failed escapes spread the sound through gameplay videos and short-form edits, where it became shorthand for being hunted. It remains popular because the rising beeps need no context to feel threatening.
