The clip is a brief Portuguese voice line saying 'não tenho moes', lasting about three and a half seconds. The words are plain and direct, with the emphasis on not having something, which makes it feel blunt, awkward and a little funny. It works as a dry refusal, the kind of short answer that lands because it offers no excuse and no extra explanation.
