The Happy Dolphin Rainbow meme, often featuring a majestic dolphin jumping over a vibrant rainbow in a vaporwave or 90s aesthetic, gained massive popularity through its ironic use on platforms like TikTok and Twitter. The trend typically involves pairing the beautiful, serene imagery with captions that are unexpectedly dark, sarcastic, or deeply personal—most notably associated with the song 'Symphony' by Clean Bandit. This juxtaposition of blissful marine life and existential dread has made it a staple of modern internet humor, evolving from simple aesthetic art into a versatile tool for comedic contrast.
