Place it at the peak of a reveal, after the setup and before the reaction shot, then follow it with Baby Laughing Meme for a baby clip or Yaaaay Cheer when a surprise lands well, keeping that beat as the centre of the edit.
About this sound
This just-under-ten-second clip is IShowSpeed reacting with a drawn-out, high-pitched 'aww so cute' that builds from soft surprise into loud, playful enthusiasm. It feels funny and genuinely warm, because the sudden sweetness cuts against his usual loud energy. The moment comes from one of his livestream reactions.
