The Dexter meme originates from the classic Cartoon Network series Dexter's Laboratory, which debuted in the mid-90s. The show follows a boy genius who operates a secret lab in his bedroom while constantly dealing with the antics of his meddling sister, Dee Dee. Memes involving Dexter typically focus on his exaggerated facial expressions, his distinct accent, or specific iconic moments like the 'Omelette du Fromage' episode. It has evolved into a staple format for expressing pseudo-intellectualism, social frustration, or nostalgia for 90s animation. Today, it remains a versatile template used across social media to react to everything from academic failure to relatable daily struggles.
