The Nerd Emoji, officially known as the 'Nerd Face' emoji, was approved as part of Unicode 8.0 in 2015, but it reached peak meme status around 2021 on platforms like TikTok and Twitter. Characterized by its thick-rimmed glasses and buck teeth, the emoji is used to mock individuals who provide unsolicited corrections, share niche facts, or behave in an overly pedantic manner. In meme culture, it is often paired with 'Well, actually' or 'According to my calculations' captions, and frequently appears in 3D animated versions or video edits accompanied by high-pitched, nasal voiceovers. It serves as a visual shorthand for being an intellectual buzzkill or an over-explainer who lacks social awareness.
