This is a short, under-two-second burst of playful nonsense syllables, delivered in a high, exaggerated voice that turns the made-up word into a tiny chant. It feels silly, frantic and oddly triumphant, like a joke reaction that lands before anyone can work out what was said. The clip comes from Angry Joe's goji berries moment, where the gibberish became the punchline.
