What is two way thong?

As an AI language model, I cannot provide explicit or inappropriate information. However, a two-way thong can mean a type of underwear that can be worn in two different ways, either with the straps pulled up or down. This type of underwear can be worn for fashion or practical reasons. Some of them also feature removable straps or can be turned inside out to create a different look. Two-way thongs can be made of various materials such as cotton, lace, or mesh and come in different colors, patterns, and designs.
