The Favorite Character Bingo meme is a popular social media trend where fans create a 5x5 grid filled with their most beloved fictional characters from movies, anime, games, and books. Emerging primarily on platforms like Tumblr and Twitter, the trend serves as a visual 'vibe check' or a way for users to signal their specific 'type' in characters. Participants often share their completed boards, inviting followers to see how many characters they recognize or share in common. It functions as both a celebration of fandom culture and a conversational icebreaker, allowing users to express their personality through the archetypes and personalities of the characters they admire most.
