Place it at the end of a reaction sequence, right after the failed moment plays out in full. Follow it with the ai que burro da 0 pra ele button for a second Brazilian TV put-down, or precede it with a DJ airhorn for an exaggerated build-up before the letdown.
About this sound
The clip is Rodrigo Faro delivering the Portuguese line 'Que cara mais sem graça' in a short, pointed TV moment lasting just under three seconds. It gives listeners an amused, mocking feeling, perfect for calling out a dull or unimpressed expression. The sound comes from Brazilian television.
