While the word, rag, has referred to scraps of cloth, a couple more incarnations of the word make for interesting contrasts. Rag-time became a musical genre in the 1890s. Rag was used to describe syncopation. Then in the last 30 years it means to be petulant and angry. The term itself was a reference to the mood changes women experience with menstruation; though now it’s used equally for both sexes.
