up the skirt

Upskirting or upskirt photography is the practice of taking nonconsensual photographs under a person's skirt or kilt, capturing an image of the crotch area, underwear, and sometimes genitalia. An "upskirt" is a photograph, video, or illustration which incorporates such an image, although the term may also be used to refer to the area of the body inside a skirt, usually from below and while being worn.
The practice is regarded as a form of sexual fetishism or voyeurism, and is similar in nature to downblouse photography. The ethical and legal issue relating to upskirt photography is one of a reasonable expectation of privacy, even in a public place.
