G-string is an Americanism first used to describe an Indian's loin cloth or breechclout in the 19th century. It could be that some fiddler in the West compared the heaviest of violin strings, the G string, to the length of sinew or gut the Indians tied around their waists to hold up their breechclouts

@SW-User Interesting. I was surmising it may have meant Genitals covering.
