The Mega Rage Face, often referred to as Rage Guy or 'FFFFFFFUUUUUUUUUUUU,' is the face that launched the Rage Comic phenomenon in late 2008. Originating on 4chan's /b/ board, this crude MS Paint drawing depicts a character in a state of extreme anger and frustration, typically following a relatable but minor misfortune. It served as the foundation for a vast library of 'Rage Faces' that dominated internet culture in the early 2010s. Even years later, the Mega Rage Face remains a timeless symbol of universal annoyance and the ultimate reaction to life's most irritating moments.
