Filthy Frank was the chaotic YouTube persona created by George Miller, later known musically as Joji, built around surreal sketches, rants and gross-out characters like Pink Guy in the early 2010s. Clips from the channel spread far beyond its original audience as reaction sounds on forums, Discord servers and meme pages. This laugh became a reusable shorthand for finding something stupidly funny, surviving long after Miller retired the character in 2017 because editors kept recycling its most exaggerated moments into new contexts.
