The Tarzan yell has been a pop culture staple since Tarzan films popularised the character created by Edgar Rice Burroughs in 1912, with its distinctive rising cry copied in cartoons, adverts and parodies for decades. Pairing that yell with a last second tree warning turned the jungle swing into a reusable internet gag. On soundboards and in short videos the clip now signals an avoidable accident, shared whenever someone heads confidently toward an obvious obstacle and fails in a loud, theatrical way.
