Joseph Joestar is the flamboyant protagonist of Battle Tendency, the second part of JoJo's Bizarre Adventure, where his exaggerated English exclamations became a running trait. His Oh No and similar shouts stood out in the Japanese series and were widely clipped by anime fans online. Short reaction sounds taken from those scenes spread through meme edits, gaming videos and soundboards, where the line became shorthand for dawning horror. It remains popular because new viewers keep discovering Joseph's expressive delivery and reusing the clip for modern formats.
