Place it at the end of a back-and-forth, after the repeated question has played out, so it lands as the final word. Follow it with Shut Up Mom for a second hit, or open with You What when the other person keeps talking.
このサウンドについて
This is a two-second spoken line delivered in a flat, irritated voice, with the insult landing hard at the end. It feels blunt and confrontational, the kind of reply that shuts the other person down instantly and makes the room laugh at their expense. The delivery is short, direct and deliberately rude, so it works best as a single sharp comeback rather than a longer exchange.
