Put it right after the reveal in your edit, following Oh My God Wow for the shock and before Nelson's Ha-Ha for the mocking laugh, so the agreement becomes the punchline before the teasing starts.
O tym dźwięku
This is a short 1.8-second voice clip of someone saying 'Ah ouais ouais ouais' — French slang for 'oh yeah, yeah, yeah' — with the word repeated three times for emphasis. It feels excited and triumphant, like a sudden realisation or an enthusiastic agreement landing all at once. The repetition makes it sound playful and over-the-top rather than calm.
