Place it right after the loudest bite in a food or reaction edit, so it answers the noise instead of introducing it. Follow it with Nope for a short, dismissive ending, or put a quiet reaction beat before it when the eating has already gone on too long.
About this sound
This is a short spoken warning, just over two seconds long, in which a voice tells someone directly to stop eating nearby. The delivery is blunt and irritated, with the emphasis landing on the food and the closeness. It feels awkwardly funny, like catching a real moment of annoyance, and works best as a quick, relatable reaction to noisy eating.
