Okaka comes from Toge Inumaki, a supporting character in Jujutsu Kaisen, the manga by Gege Akutami and its anime adaptation. Because his cursed speech can force listeners to obey his words, Inumaki limits himself to the names of onigiri fillings, and okaka, meaning dried bonito flakes, is one of those safe words. Clips of his short, distinctive lines spread among anime fans on video and meme pages, where they are reused as reactions, edits and inside jokes long after their original scenes.
