Place it as the last sound in a short edit, after the argument has played out and the other side has had its say. Let No No Wait Wait stall the reply first, then follow it with this clip to close the exchange, and let the verdict stand on its own.
このサウンドについて
This 3.6-second clip is a voice delivering the Italian phrase 'punto e basta' in a firm, clipped tone, as if shutting a question down for good. It feels final, blunt and a little smug, the sound of someone refusing to argue any further. It comes from Marco Merreact's 'Le Domande dei Vegani agli Onnivori!'.
