Place it at the end of the setup, right before the failure is shown, then follow it with a reaction sound that confirms the disaster. Pair it with Emotional Damage after the fallout, or Bruh for a flat response to the bad decision.
About this sound
This is a short 1.5-second Portuguese line from Captain Nascimento in Tropa de Elite, delivered as a blunt warning that something is about to go badly wrong. It feels tense and ominous, with a dry humour that makes the coming disaster feel inevitable, so it lands as both a serious alert and a joke about a plan falling apart.
