Place it just before the moment of failure in an edit, so it acts as the warning, then follow it with a reaction sound such as No God Please No when the outcome lands, or cut to FNAF Jumpscare Scream for a sudden shock after the prediction.
About this sound
This short clip delivers the Japanese line 'Omae wa mou' in a low, deliberate voice, stretched just long enough to let the threat sink in before the implied finish. It feels ominous and theatrical, with a deadpan menace that turns a serious moment into a joke when it lands out of context. The line is the well-known 'you are already dead' moment from Fist of the North Star.
