What is "air kiss"

n. A social gesture in which the lips are pursed as if kissing, but without actual contact.

The air kiss is a ritual or social gesture whose meaning is basically the same as that of many forms of kissing. The air kiss is a pretence of kissing: the lips are pursed as if kissing, but without actually touching the other person's body. Sometimes, the air kiss includes touching cheek-to-cheek. Also, the gesture may be accompanied by the mwah sound. The onomatopoeic word mwah has entered Webster's dictionary.
