Place it immediately after the daft claim in your edit, so the insult answers the speaker directly. Follow it with the Damn sound for a second reaction, or lead into it with No No Wait Wait when you want the speaker to pause first.
About this sound
This under-two-second voice clip captures Rudo Vaský snapping the Slovak insult in a sharp, exasperated tone, with each word landing like a slap. It feels blunt, confrontational and darkly funny, the kind of outburst that makes a daft remark feel instantly shut down. The line is credited to Vaský, whose delivery turns a crude insult into a memorable reaction.
