The roar comes from Legendary's 2014 Godzilla film, in which the giant monster returns to the screen in a more grounded, realistic reboot. The airport moment became one of the film's most shared sequences because it shows the creature's scale against ordinary surroundings. Fans ripped and shared the roar on soundboards and video platforms, where editors began using it as shorthand for something huge arriving. It remains popular because the sound is instantly recognisable even without the picture.
