The original video behind this line is not documented, so it is best understood as a short Spanish internet reaction clip rather than a line from a known film or series. Its slang, especially the final word, gives it a casual Mexican street-talk feel that Spanish-speaking creators recognise instantly, and its short length makes it easy to drop into edits, prank compilations and reaction videos. Because the delivery is so direct and the phrase is easy to repeat, it has survived as a shorthand for disbelief, spreading mainly through soundboards and short-form video rather than through any viral post.
