Place it at the very end of a scene, right after the final refusal, so it closes the exchange instead of opening another one. Follow it with awkward crickets to underline the exit, then bring in a lighter clip if the next scene needs to reset the mood.
About this sound
This short voice clip delivers a flat, fed-up 'I'm done, nope' in a tone that sounds like someone closing a conversation for good. It lands as a funny, relatable shutdown, perfect for that moment when arguing further feels pointless and walking away feels better. The clipped delivery makes the refusal feel final without needing any extra explanation.
