The Tarzan yell dates back to the early Tarzan films of the 1930s, where Johnny Weissmuller's ululating cry became the character's signature, and Disney gave it new life in its 1999 animated Tarzan. The call escaped the movies through cartoons, commercials and comedy sketches before landing on soundboards and meme edits. Today it sits alongside other meme entrance staples like the Vine Boom and the air horn in countless edits, surviving because three seconds of that yodel instantly signals wild jungle adventure.
