The 'I Hate Stuart Little' phenomenon is an internet subculture rooted in ironic, hyper-aggressive hatred toward the protagonist of the 1999 film Stuart Little. What started as niche shitposting on platforms like Reddit and Tumblr grew into a massive movement where users jokingly blame the mouse for various historical catastrophes and societal ills. The humor lies in the sheer absurdity of harboring such intense, vitriolic rage toward a small, polite fictional rodent in a sweater. This meme template is typically used to express exaggerated frustration or to participate in the long-running internet tradition of making Stuart Little's life as difficult as possible through satirical captions.
