The 'I Believe in Supremacy' meme emerged as a popular way for internet users to signal their intense loyalty or preference for a specific person, character, or concept. Usually featuring a refined character in formal attire or a minimalist aesthetic, the template communicates a sense of unwavering, almost cult-like devotion presented with a touch of irony. It gained significant traction on platforms like Twitter and TikTok, often used within fandoms to crown a 'best girl' in anime or to celebrate niche hobbies. The phrase itself has become a staple of internet slang, used to elevate a subject above all competitors in a humorous, hyperbolic fashion.
