The McDonald's Adult Happy Meal meme took the internet by storm in late 2022 following the collaboration between the fast-food giant and the streetwear brand Cactus Plant Flea Market. Characterized by four-eyed versions of classic mascots like Grimace, the Birdie, and the Hamburglar, the campaign tapped into millennial nostalgia, sparking a wave of viral content across social media. Users often use this template to poke fun at the irony of being an adult with real-world responsibilities while still finding genuine joy in a plastic toy and a cardboard box. Whether highlighting the chaotic energy of the redesigned toys or the high demand that led to store shortages, the meme serves as a humorous commentary on consumer culture and the enduring power of childhood memories.
