Tarzan was created by Edgar Rice Burroughs and first appeared in print in 1912, before film versions made his jungle yell one of cinema's most copied cries. The long, warbling call became linked to the character through the 1930s Tarzan movies and was later parodied in cartoons, adverts and comedy sketches. Online, creators pitch and speed up the yell to make it sound more frantic and absurd, turning a heroic signal into a short meme sound for swings, jumps and mock-heroic moments shared in edits and group chats.
