Estão enganadas is a Portuguese phrase meaning they are mistaken, and the clip circulates online as a standalone reaction rather than as part of a longer known recording. Its exact source is not widely documented, so it has spread mainly through soundboards and short video edits where context does the work. Brazilian and Portuguese speaking users share it in group chats and comment threads, and its blunt tone has helped it survive as a quick meme reply when an argument, prediction or claim turns out to be wrong.
