Bahaghari = rainbow

Filipinos usually associate the word “bahág (loincloth/g-string)” with the traditional attire of a male Igorot/Ifugao (an ethnic group in the northern part of the country). In Baguio City, the capital of the Mountain Province, you can see some Igorot men wearing them.
The thick cloth’s usual design is bold-color stripes, and that’s how the metaphor came about.
So, “bahaghari” is “bahag + hari -> bahag ng hari = loincloth of a king”.
