Place it immediately after the repeated line or joke that needs shutting down, so it acts as the cut-off in the middle of an edit. Follow it with a Nope clip to close the exchange, and save the Okay Let's Go clip for a later scene where the action actually starts again.
关于此声音
This 0.4-second clip is a single voice saying 'Please stop,' with nothing else around the words. It feels exasperated and awkward, like someone who has asked once too often and is done being polite. That blunt, worn-out edge makes it funny in the right moment, turning a plain request into a clear signal that enough is enough.
