Place it at the end of a failed attempt, after the mistake is visible and before any commentary. For a bigger reaction, lead in with No No Wait Wait and follow it with Oh My God Wow, so the refusal builds into surprise. Keep it as the single reaction beat in a short edit.

The clip is a short vocal reaction lasting just over two seconds, built around one stretched-out cry of 'ah naooo' credited to Jaoo. The drawn-out delivery makes the refusal sound dramatic and overdone rather than calm, giving it a comic, exasperated feeling that suits a small disaster. It lands as a playful groan of disbelief, the kind of sound that turns bad news into a joke.
