Place it at the end of a short exchange, after a setup clip such as No No Wait Wait lets the other person dig themselves in, then follow it with Damn to underline the reaction before cutting to the next scene.
关于此声音
This 9.5-second clip repeats the blunt Portuguese exclamation VTNC twice in quick succession, as a short vocal reaction. It feels confrontational, dismissive and deliberately over the top, like shutting a conversation down with no room for a reply. The repeated wording makes the dismissal land harder than a single use would.
