Place it immediately after the reveal in a reaction edit, letting the guilty moment sit first, then follow it with Oh My God Wow to escalate the reaction. For a slower tease, open with Ceeday Huh and let this clip answer it, keeping the focus on the reaction rather than the setup.

This clip is a short human voice repeating uy again and again for about five seconds, each syllable quick, bright and rising in the same playful rhythm. It feels cheeky and teasing, like a mock gasp stretched into a chant, landing as light surprise rather than alarm. The repetition makes it easy to recognise and fun to drop into a silly moment.
