Place it right at the reveal or bad decision in your edit, before any response line. Follow it with the Bruh Soundboard Button for a flat reaction, then add the Emotional Damage Sound Button when the consequence lands and the scene needs a second punch.
About this sound
A short 1.4-second voice clip of someone shouting 'não, não, nãoooo' over and over, stretching the final no into a wail. It feels panicked, overdramatic and funny at once, like a refusal that keeps getting louder instead of calmer, turning a simple no into a full meltdown moment for the listener hearing it.
