This is a short, under-two-second comedic effect built around a rounded, wobbling booyooy vocalisation that bends like a cartoon spring. It lands as a light punchline rather than a heavy hit, giving a small awkward moment a playful, slightly absurd lift. It makes a failed move or odd expression feel deliberately sillier without turning the scene dramatic.
