Charlie Brown is the long-suffering hero of Charles M. Schulz's Peanuts, a comic strip that later became a series of beloved animated specials. His exasperated yell has become shorthand online for bad luck and everyday frustration, because viewers instantly recognise the character and his habit of losing out despite his best efforts. Shared widely on soundboards and in short-form edits, the short shout works as a quick, wordless reaction that needs no explanation for anyone familiar with Peanuts.
