This is an ultra-short blah sound effect lasting just a fraction of a second, a flat spoken noise that cuts in and stops. It feels dismissive and silly, like waving off rambling talk without actually arguing. The clip is credited to Vinesauce Joel and his Color Fun material, which is how this tiny blah started circulating as a reaction.
