The 'Rainbow Road Song' meme stems from a humorous fan-made track by YouTuber Nathan Provident, specifically a parody of the Rainbow Road theme from Mario Kart Wii. The song gained massive viral traction on platforms like TikTok and Instagram due to its unexpectedly dark lyrics: 'It's called the Rainbow Road, it's a road that you go when you die.' It is primarily used as a soundtrack for gaming fail compilations—specifically moments where a player falls off the edge of a track—or as a humorous way to signify an impending disaster in various real-life scenarios. The contrast between the bright, cheerful aesthetic of the Rainbow Road track and the existential nature of the lyrics has made it a staple in the gaming community's repertoire of irony and dark humor.
