The Arthur Fist meme is a reaction image featuring a close-up of the protagonist Arthur Read from the animated children's TV series Arthur clenching his fist. The screen capture originates from the 1999 episode Arthur's Big Hit, specifically the moment before Arthur punches his younger sister, D.W., for breaking his model airplane. The image went viral on Twitter in mid-2016, quickly becoming a universal symbol for suppressed anger, relatable frustration, and 'internal screaming' in response to various annoying real-life scenarios.
