Place this clip at the turning point of the edit, after a sudden suspense sound effect builds the beat and just before the reaction shot lands. Follow it with a no no wait wait clip for backpedalling, or a Nelson ha ha for the payoff from onlookers.
About this sound
This is a long dramatic voice clip built around a man delivering the line 'and now you're going to die' in a menacing, theatrical way, with a follow-up reference to knives. It feels tense and threatening on the surface, but the delivery is so exaggerated it lands as campy and funny, like a fake villain reveal rather than a real danger.
