Domain Expansion is a high-level cursed technique in Jujutsu Kaisen, the manga and anime series created by Gege Akutami, in which a sorcerer creates a separate space where their attacks are guaranteed to hit. Espansione del Dominio is the Italian dub wording for the technique, and clips of the announcement have spread through Italian anime edits, TikTok videos and meme compilations. Fans reuse it because the phrase instantly signals overwhelming power, even for viewers who do not follow the series closely.
