Esto es una burla translates literally as this is a mockery, and in online use it works as a Spanish-language reaction to something perceived as fake, forced or absurd. No single film, show or creator can be confidently credited as its source from the information available, so its spread is best understood through meme and reaction-video culture, where short Spanish voice clips travel easily between edits, duets and commentaries. Its staying power comes from its bluntness: the phrase names the joke directly, making it a quick shorthand for disbelief that does not need a long setup.
