A kiss is the touch or pressing of one's lips against another person or an object. Cultural connotations of kissing vary widely. Depending on the culture and context, a kiss can express sentiments of love, passion, romance, sexual attraction, sexual activity, sexual arousal, affection, respect, greeting, friendship, peace and good luck, among many others. In some situations a kiss is a ritual, formal or symbolic gesture indicating devotion, respect, or sacrament. The word came from Old English  (“to kiss”), in turn from coss (“a kiss”).

Kisekae Set System (commonly known as KiSS) is a blending of art with computers originally designed to allow creation of virtual "paper dolls". Kisekae is short for "kisekae ningyou"; a Japanese term meaning "dress-up dolls". Unlike "computer art" which creates or displays traditional art via a computer, KiSS uses the computer as the medium, allowing the art to be not only animated, but also interactive.

A kiss is a touch with the lips, usually to express love or affection, or as part of a greeting.
