The Smiling Dolphin meme, often associated with the song 'Symphony' by Clean Bandit, features a vibrant, CGI-style dolphin jumping gracefully against a sunset and rainbow backdrop. It gained massive popularity on TikTok in 2024 as a form of ironic humor. Users typically pair the overly cheerful and majestic imagery with incredibly bleak, depressing, or unhinged captions. The humor stems from the jarring contrast between the dolphin's blissful, inspirational environment and the text's dark reality, making it a staple for expressing Gen Z nihilism and existential dread in a colorful, absurd way.
