Place it immediately after the foolish claim in the edit, then follow it with the Damn meme for a second reaction, and finish with Oh My God Wow before the next scene starts.
O tym dźwięku
This is a 2.3-second German dialect voice clip built around the spoken phrase Scheiß Huankind Oida, delivered as a blunt, exasperated reaction to foolish behaviour. It lands with a weary, eye-rolling humour that makes the insult feel playful rather than angry, perfect for calling out nonsense without starting a real argument.
