The Rainbow Dolphin meme, often associated with the song 'Symphony' by Clean Bandit, gained viral status on TikTok and Instagram in mid-2024. Featuring a hyper-realistic, sparkling dolphin leaping over a vibrant rainbow, the image is frequently paired with incredibly dark, existential, or mundane captions to create a stark contrast between the visual's extreme positivity and the text's bleakness. This trend, often referred to as 'corecore' or 'hope-posting' irony, uses the dolphin's majestic leap as a backdrop for expressing thoughts of quitting, failing, or simply giving up, making it a staple of modern internet surrealism.
