Put it at the end of a failed-play clip, after Ah Shit Here We Go Again sets up the mistake and before Nope closes the sequence, so it lands as the payoff rather than the opening. Keep Enemy Spotted for the moment the threat first appears, earlier in the same edit.

This is a two-second spoken clip built around the internet shorthand KYS, delivered as a flat, direct address with no extra words or music behind it. It lands as a hostile, mocking put-down, used to shut down a bad play or a foolish comment rather than to tease it gently. Its bluntness is the point, making it feel confrontational, unsympathetic and uncomfortable for the person it is aimed at.
