GO! GO! MANIAC is the hyper-energetic first opening theme for the second season of the beloved slice-of-life anime K-On!!. Performed by the fictional band Ho-kago Tea Time, the song is famous for its exceptionally fast tempo and Yui Hirasawa's rapid-fire vocals. In the meme world, it is often used to represent moments of extreme excitement, ADHD-like energy, or frantic obsession with a hobby. Fans utilize the title and the high-speed visuals from the animation to parody how it feels when a person 'goes maniac' over their favorite things, whether it's tea, cake, or music gear.
