Place this clip right after the on-screen assignment and before the attempt itself, then follow the failed result with No No Wait Wait for a second protest, or end the sequence there if the attempt cuts away early.
About this sound
A 1.3-second Portuguese voice clip of a woman blurting 'Peraí, eu não tô treinada!' — wait, I'm not trained. The delivery is rushed and flustered, turning a simple admission of being unprepared into a funny, caught-off-guard reaction that lands instantly when someone is pushed into a task they clearly have not practiced for at all.
