Place it at the end of a pitch segment as the final reaction, after the offer is shown on screen. Follow it with the law and order dun dun sting for a serious verdict beat, or precede it with a windows xp error sound to set up the failed pitch.
About this sound
This is a short voice clip, about 2.7 seconds, built around the blunt insult 'idiot con artist' delivered like a verdict on a bad pitch. It feels sharp, dismissive and darkly funny, the kind of line that lands as both an accusation and a put-down. It comes from the television world of Shark Tank business pitches.
