About this sound
This is a short Portuguese voice clip of about five seconds, built around the spoken line Eu não sou assim and the Bistecone name, delivered as a firm denial. It feels funny and indignant, like someone caught in a joke they refuse to own, and it works because the refusal sounds immediate and personal.
