Put it at the end of a short confrontation, after the other person has made their claim, so it closes the exchange. Lead in with Enemy Spotted when a stranger approaches, then let this clip answer them, and follow it with Nope if they keep pushing.

This four-second clip delivers the line 'I don't know you, and I don't care to know you' in a flat, dismissive voice from Oblivion. It feels cold, awkward and funny at once, like shutting a door on a stranger mid-sentence. The blunt delivery makes the rejection land harder than the words alone.
