Put this clip right after the reveal or boast in your edit as the reaction beat, preceded by a WhatsApp message ping to set up the chat context, then follow it with the Kiko Laugh as the payoff so the sequence builds from tease to full laughter.

This clip is a single stretched-out vocal exclamation, a voice holding the sound 'uuuuiiiiiiiiii' for just over a second with rising, playful energy. It feels teasing and exaggerated, like a drawn-out whistle of surprise or admiration that turns a small moment into a joke and makes listeners react along with the sheer over-the-top delivery.
