Filthy Frank was the surreal YouTube comedy persona of George Miller, later known as Joji, whose sketches and rants became a major source of early internet meme audio. This weeaboo clip spread through soundboards, reaction videos and short-form edits, where fans reused Frank's confrontational style to call out exaggerated anime fandom. It remains popular because the insult is instantly recognisable to meme audiences and pairs well with similar anime reaction sounds like anime ahh and Onii-chan, onii-chan, giving editors a quick shorthand for mocking over-enthusiastic fandom without needing context.
