Place it right after the birthday plan reveal in an edit as the closing response, then follow it with a bruh for the reaction beat. For a sadder turn, bring in the sad meow song under the next scene instead of stacking another voice clip on top.
About this sound
A five-second voice clip of a man flatly saying he does not want to celebrate his birthday anymore, delivered as a single tired statement. It feels funny, awkward and relatable, like the exact moment the party mood collapses and someone has finally had enough of the celebration.
