The phrase in the title is Brazilian Portuguese, and zoeira is slang for joking around or messing with someone, which fits how the clip is shared online. No single creator, show, or original video is clearly documented for this short shout, so it is best understood as a circulating reaction sound rather than a quote from a known work. Its appeal is its brevity and attitude: under two seconds, it delivers mock annoyance in a form that is easy to drop into edits, streams, and group chats. That portability has kept it useful for Portuguese-speaking meme communities.
