Place it at the end of a rejection scene, right after the unwanted line, then follow it with the Vine Boom sound to close the scene. For a slower build, open with the Dun Dun Dun sound before the dismissal, so the rejection lands as the payoff.

The clip is a single spoken 'get lost', delivered in one flat, dismissive burst lasting just over a second. It lands as a blunt, comic brush-off, sharp enough to sting but short enough to feel playful rather than cruel. The tone makes it useful for exaggerated rejection, turning an awkward interruption into a quick laugh.
