Place it at the end of a setup, right after the question or bad idea has been heard in full, so the refusal closes the scene. Pair it with a buzzer for a wrong answer, or follow it with a bruh when the idea was especially hopeless, letting the second reaction underline the first.

This is a short German voice clip saying 'Definitiv nein', or 'definitely no', in a firm, clipped tone that lasts about three seconds. It lands as a blunt, final refusal with no room for argument, making it feel dryly funny rather than angry. That flat certainty makes it feel like a door closing on the discussion.
