The 'Smart Guy With Glasses' meme features Yan Toples (Yan Lapotkov), a popular Russian science and educational YouTuber known for his highly produced videos exploring complex topics. The template, showing Yan looking thoughtful or gesturing during an explanation, became a viral symbol for someone sharing 'galaxy brain' facts or being overly pedantic. Originating in the Russian-speaking digital community, it evolved into a universal tool for depicting someone explaining niche interests or pseudo-scientific theories with unearned confidence. It is most commonly used to mock those who offer unsolicited, long-winded explanations for simple concepts or to highlight the absurdity of modern online discourse.
