What are "underpants"?

Underpants, also known as underwear or briefs, are a type of undergarment worn on the lower part of the body, covering the buttocks and genital area. They can be made from a variety of materials, including cotton, silk, and synthetic fabrics, and are available in many different styles and designs for both men and women. Underpants can be designed with different levels of coverage, including high-waisted, low-rise, and thong-style, and may have additional features such as built-in support or moisture-wicking properties. They are typically worn for hygiene and comfort reasons and are often considered an essential item of clothing.
