Ryomen Sukuna is the main antagonist of Jujutsu Kaisen, a manga and anime series created by Gege Akutami, known as the King of Curses. Online, the slang term tweakin describes someone acting wild, erratic, or losing control, and editors have applied it to short Sukuna clips that exaggerate his most unhinged moments. Those edits spread through TikTok, anime meme pages, and soundboards, where the two-second burst became a shorthand for chaotic energy. It remains popular because it instantly signals a villain breaking character in a funny, over-the-top way.
