Place it immediately after the unwanted offer is shown, so the refusal becomes the punch of the scene, then follow with Eww Brother Eww for a second reaction or No No Wait Wait when the character tries to backtrack. Use it once per edit to keep the refusal sharp.

It feels funny and awkward, like a blunt rejection delivered with too much honesty, and it works because the speaker sounds genuinely put off rather than playful.
