The lyrics describe the man's sheer astonishment at witnessing the double rainbow and his inability to fully comprehend its intensity and beauty. The repeated phrase "Double rainbow, oh my God, double rainbow" illustrates his overwhelming excitement. The song also humorously suggests that the double rainbow is so intense that it starts to resemble a triple rainbow, further emphasizing the man's awe. There is a sense of disbelief and wonder throughout the lyrics as the man exclaims, "What does this mean? It's so bright, so vivid."
