The upskirt is when a woman intentionally or accidentally exposes her underwear or bare genitals under her skirt or dress. When intentional, public nudity and upskirts are acts of exhibitionism, where the one exposing him- or herself gets a sexual thrill by showing off parts of the body usually clothed in public. Public nudity, depending on local ordinances, may or may not be legal, but it is usually not; hence the thrill for the exhibitionist. Persons engaging in public nudity get aroused by exposing themselves on public walking trails or along roadsides, or even in sidewalk cafes or parking garages. They may or may not engage in sexual activity while being out and about nude.
