Put this clip last in a reaction sequence, after the setup line has played in full and before you cut away. Follow a failed excuse with the bruh sound first, then end on this dismissal so the conversation closes instead of continuing.
關於此聲音
This is a 1.6-second spoken clip of the French line Ren ! Mais on s'en bat les couilles ! delivered as a blunt shout. It gives a listener a feeling of total indifference, because the speaker shuts the subject down completely instead of arguing about it, which makes the dismissal feel funny and final rather than explanatory.
