The word comes from “Muggle” in the Harry Potter series, where it refers to a person without magical powers. In Korean fandom and internet culture, it spread as a handy contrast to 덕후, meaning someone outside a fandom or niche interest. The exact moment it entered everyday Korean fan slang is unclear, but it became familiar as the series gained popularity in Korea from the late 1990s into the 2000s.
