Lobotomy Kaisen refers to a period of intense, surreal, and nonsensical shitposting within the Jujutsu Kaisen community, primarily triggered by long manga hiatuses and shocking plot developments. The term describes the 'brainrot' experienced by fans who began creating increasingly absurd memes, characterized by distorted visuals and recurring catchphrases like 'Nah, I'd win' or 'Are you the strongest because you're Satoru Gojo?' It represents a subculture of humor where high-stakes shonen drama is transformed into chaotic, repetitive irony. This phenomenon solidified JJK as a powerhouse of internet culture, turning tragic character moments into inescapable, hilarious templates used across TikTok, Twitter, and Reddit.
