The Crazy Rhubarb Lady meme originated from a viral 2013 YouTube video titled 'Alley Cat - Rhubarb Lady,' which captures an intense and bizarre neighborhood dispute over allegedly stolen rhubarb. The woman in the video became famous for her eccentric insults, including calling her neighbor a 'pinhead' and a 'loser' while claiming she is the queen of the neighborhood. This template is widely used to represent irrational anger, entitled behavior, or chaotic energy in everyday situations. Memers often use it to depict someone overreacting to a minor inconvenience or to highlight Karen-like behavior from the early internet era.
