Put it at the end of a rambling clip, after the speaker has had their say, so it closes the exchange. Lead in with No No Wait Wait for the desperate plea, then cut to this clip, and finish with Damn for the group's reaction to the shutdown.

This is a very short spoken clip, lasting about a second and a half, in which a voice delivers the blunt line 'shut up bitch' with no hesitation. It feels confrontational and deliberately rude, the kind of interruption that lands as a joke when the timing is right and as a sharp put-down when it is not. Its abruptness makes the dismissal feel final.
