The charge is a traditional military bugle call once used to order cavalry into an attack, with its short, repeating notes designed to carry clearly across a noisy battlefield. Western films and cartoons later borrowed it as instant shorthand for a heroic advance, and that screen use fixed it in popular culture far beyond its military origins. Online, creators now reuse the same few seconds as a punchline for any sudden rush, entrance or competition, because almost everyone recognises the tune even without knowing its history.
