Place it as the reaction beat right after the mistake in your edit, then follow it with Fail Sound Meme to underline the flop before moving on. For a second reaction later in the same video, use Bruh Meme so the two responses do not repeat each other.

This is a short 2.7-second clip built around a single flat 'bruh', delivered in a low, drawn-out voice with no music or other effects behind it. It lands as deadpan and dismissive, the kind of weary reaction that makes an awkward moment funnier by refusing to react to it properly.
