Place it right after the mistake in your edit, following a short reaction from No God Please No, then let Nope close the scene. That order builds the fail, adds the payoff, and ends on a flat refusal that keeps the joke tight.
About this sound
This 11-second clip pairs a smug, taunting laugh with a repeated oh no no no voice, built around the classic troll face energy. It feels mischievous and chaotic, like someone enjoying a prank just as it goes wrong. It comes from the long-running troll face rage-comic meme, where the grinning face became shorthand for obvious trolling across internet culture.
