Cuscuz is a staple cornmeal dish in Brazil, especially in the Northeast, which makes the phrase instantly familiar to Portuguese-speaking audiences. The Sebastião tem cuscuz clip circulates on Brazilian soundboards and social edits as a short standalone voice meme, shared without a clear single source. Its spread comes from how easily the line can be inserted anywhere, turning an ordinary name and food pairing into a running joke. It remains used because the wording is specific enough to be recognisable but random enough to fit almost any pause.
