The clip is linked to Inês Brasil, a Brazilian singer and internet personality whose exaggerated, theatrical performances made her a recurring figure in Brazilian meme culture. Her expressive delivery and distinctive voice lend themselves to reaction videos, where a single dramatic line can carry an entire joke. Shared through short-form video edits and social clips, the phrase se esse mundo existe became a shorthand for disbelief at something absurd or unexpected. It endures because the emotion is clear even without translation, making it easy to reuse across different jokes and contexts.
