Put this clip right on the cut where a plan falls apart, then let a bruh reaction land underneath the stunned moment before you add a faaah burst for a second, bigger escalation in the next beat of the edit.

This is a short 1.5-second vocal clip built around a single stretched 'cacaaaa' syllable that keeps extending well past where you expect it to stop. The effect is silly and jarring in a harmless way, turning a tiny throwaway noise into an absurd interruption that listeners tend to hear as a deliberate, over-the-top reaction.
