"Sono do diabo" is commonly shared as a Brazilian meme audio in short-form edits, reposts, and chat groups. Its exact original source is not clearly established from the available facts, so it is best understood through its online use rather than a confirmed character or show. The clip spread because the phrase is short, expressive, and instantly readable even for quick reaction videos. It remains popular in Portuguese-speaking meme culture for jokes about tiredness, burnout, ugly sleep schedules, and mornings that start badly.
