Place it after the reveal of the failed deal, as the closing reaction in a short edit, then follow it with the Bruh sound for a second reaction and the Emotional Damage sound if the loss gets worse. That order keeps the joke moving from the deal itself to the person who made it.

Reccon Deal Doh is a meme sound lasting about 16 seconds, built around a spoken deal gone wrong and a resigned doh that sums up the whole failed arrangement. It lands as comic frustration, the kind of groan you make when a plan collapses in front of everyone and there is nothing left to say except that one defeated sound.
