The FFFFFFFUUUUUUUUUUUU meme, better known as 'Rage Guy,' is the foundational character of the Rage Comic universe. It first appeared on 4chan's /b/ board in late 2008, featuring a crudely drawn MS Paint character reacting to the splash of toilet water. The meme traditionally serves as the final punchline to a four-panel comic detailing a relatable, everyday misfortune. Over the years, Rage Guy sparked a massive internet subculture, leading to the creation of countless other 'Rage Faces' and becoming a definitive symbol of early 2010s internet humor and the universal feeling of pure, unadulterated annoyance.
