The Smiling Buck Tooth Emoji, widely recognized as the 'Nerd Emoji,' features a yellow face with glasses and prominent buck teeth. While originally intended to represent studiousness, it has evolved into a powerful tool for mockery and irony. Online communities use it to represent the 'Well, Actually' persona—someone who corrects minor details with an air of unearned superiority. It gained massive traction on platforms like Twitter and TikTok, where users pair the emoji with pedantic arguments to satirize people who take things too literally or act as know-it-all experts in casual conversations.
