Ratinho, whose real name is Carlos Massa, is a Brazilian television presenter known for the lively, audience-driven style of his SBT variety show, where exaggerated reactions became part of his on-screen identity. The shouted Eita, a common Brazilian expression of surprise, spread beyond television as fans clipped it for WhatsApp audios, reaction videos, and short-form edits. Its appeal has lasted because the sound is instantly recognisable to Brazilian audiences and needs no translation to convey shock, excitement, or disbelief in a meme.
