Place this clip at the reveal point in your edit, right after the mistaken setup. Follow it with a bruh sound for the stunned reaction, or precede it with a scream meme to heighten the mistaken panic before the correction hits.

This is a very short voice clip, under one second long, of a male voice shouting the Japanese phrase 'Otoko da yo!' meaning 'I'm a guy!' The delivery is loud, blunt and sudden, which gives it a funny, surprising punch that works as an instant reveal or correction.
