A shorter version of a skirt, used mostly by women to make women feel good about themselves, often wrongly interpreted, as meaning they want sex. Women who wear them are often wrongly called "sluts" males who use the term so that they won't feel guilty about treating women like objects; this term is usually used by sexist men who never use the same word when referring to shorts on a male or a kilt on a male
A mini version of a skirt - miniskirt.
The above deifnition is a sexist definition used by men to apply to the miniskirts of females so that men can feel better about treating women as objects, but the same is not the case when referring to men's shorts or kilts, which shows how sexist and innacurate the definition is.
The actual definition is: A short version of a skirt, worn (usually by females) for various reasons, such as to feel comfortable in what one is wearing, to show femininity, or to look nice. Often mistaken as a sign that the person wants approaches from men, when actually they don't (or in cases where they do, somtimes this is mistaken to mean that the girl wants sex, when actually she doesn't).
