motteke! serafuku

"Motteke! Serafuku" (「もってけ！セーラーふく」) is the opening song to the anime adaptation of Lucky Star, sung by Hirano Aya, Katou Emiri, Fukuhara Kaori, and Endou Aya. Much like Hare Hare Yukai, the bulk of the animation sequence for Motteke! Serafuku features dancing.

On Danbooru, this tag refers to images that reference the opening animation. Sometimes the sequence will be associated with the Hall & Oates song "Out of Touch", due to an English-speaking Western meme combining the dance with the aforementioned song.
