Place it right after the reveal shot, before you cut away, then follow with JoJo To Be Continued for a cliffhanger or lead into Za Warudo Time Stop when the edit freezes on the chaos.
About this sound
This is Joseph Joestar shouting 'Oh my god' in a short, theatrical voice clip lasting under three seconds. It feels panicked and disbelieving but also funny, turning a small shock into something wildly dramatic. The line comes from JoJo's Bizarre Adventure, where Joseph's exaggerated English reactions became a fan favorite.
