Place it just after a setup line and before the payoff, then follow it with Michael Jackson Hee Hee for a second accent, or with Oh My God Wow when the reaction needs to grow bigger.

This is a single ad-lib lasting just under a second, a brief improvised vocal burst of the kind artists drop between lines to add emphasis. It feels playful and punchy, landing like a quick stamp on a moment rather than a full line. Use it when a reaction needs energy but no words.
