This audio circulates mainly as a Portuguese-language meme clip shared in short videos, status posts, and reposted edits about the start of the week. Its appeal comes from how quickly the phrase communicates a universal feeling: Monday has arrived, and nobody is thrilled about it. Creators keep using it because it fits everyday situations without setup, from commute videos to work jokes. Online, it often appears alongside other reaction sounds such as bruh or a buzzer when the edit leans into disappointment or instant defeat.
