In an edit, place this clip right after the accusation line on screen, then let the conversation continue underneath it. Follow it with the Huh sound for a confused beat, or precede it with the No No Wait Wait button when the claim needs stopping first.
关于此声音
This is a roughly fourteen second spoken clip of the Russian phrase 'S chego ty vzyal,' literally asking why you would think that. It is delivered as a direct challenge to an unsupported assumption. The feeling is incredulous and mildly indignant, funny because the pushback is so blunt and immediate, like a verbal eyebrow raise that calls out a claim without arguing the details.
