FFFFFUUUUU comes from Rage Guy, the stick figure star of rage comics that spread on 4chan and Reddit around 2008 and 2009. The comics ended with the character leaning back and screaming FFFFFUUUUU, short for an unfinished swear, as the perfect reaction to everyday annoyances. As rage comics became a template format, the scream was turned into audio edits and reaction clips. It outlived the comics themselves and remains a go to sound for gaming rage, fails and exaggerated frustration online.
