Place it immediately after the reveal in an edit, following sudden suspense to build the wait, then follow it with kids cheering to carry the payoff forward, and save oh my god wow for a bigger second reaction later in the clip.

This is a short spoken reaction clip, just over two seconds long, built around the line 'Yeah I been waiting for this' delivered with eager, ready-for-action energy. It feels triumphant and impatient at once, like the release after a long build-up, and it works best as an instant burst of excitement when something anticipated finally arrives.
