Place it immediately after the request or suggestion it answers, so the refusal closes that moment in the edit. Follow it with Bruh for a deadpan reaction, or with Emotional Damage when the refusal itself becomes the joke that follows.

This clip is a voice repeating the word non five times over just under six seconds, each repeat landing a little firmer than the last. It feels like a firm, comic refusal, the kind that shuts a suggestion down without raising its voice. The steady repetition makes the no sound final and a little stubborn, which is why it works as a quick answer.
