The clip circulates as a Brazilian Portuguese reaction sound, named for Sargento Pimentel, the voice heard in the short recording. Its appeal is less about a single viral video than about the phrase itself, which is a common, informal way of reacting to something disappointing or absurd in everyday Brazilian speech. That familiarity is why it travels well in memes, edits and chat replies, where a single blunt line can replace a longer explanation. It remains in use because it is short, instantly understood by Portuguese speakers and easy to drop into almost any fail.
