This short organ cue is part of the long tradition of stadium music used at baseball games and other live sports events. Variations of the charge call have been heard in arenas for decades, where organists and sound crews use it to wake up the crowd before a key moment. Online, it spread beyond sports because the melody is instantly recognizable and easy to use as a joke setup. Creators still add it to memes, scoreboards and victory clips whenever they want a classic ballpark feel.
