Motteke! Sailor Fuku is the high-energy opening theme song for the 2007 anime series Lucky Star, performed by the main cast. Known for its nonsensical, rapid-fire lyrics and iconic synchronized choreography, the sequence became a viral sensation in the early days of YouTube and Niconico. It sparked a global dance craze and remains a pillar of moe culture and late-2000s internet nostalgia. In meme culture, the template is frequently used to represent chaotic joy, group activities, or the undeniable urge to dance when a catchy song comes on. It typically features the four main characters—Konata, Kagami, Tsukasa, and Miyuki—in their signature sailor uniforms, often edited to include different characters or absurd captions about subculture life.
