Put this clip immediately after the reveal shot, then follow it with the SpongeBob Fail sound effect if the outcome flops. For a bigger build, place the Anime Wow sound effect just before it so the reaction lands first and this chant carries the rest of the scene.
About this sound
The clip is a roughly ten-second chant of the syllable po repeated in a steady rhythm, delivered in a light sing-song voice that stays playful throughout. It feels bouncy and deliberately absurd, with the humour building as the repetitions keep coming, turning an ordinary moment a little cheeky and overdone without using any actual words.
