When a man kisses the upper lip of a woman, while she in return kisses his lower lip, it is called the “kiss of the upper lip.”

When one of them takes both the lips of the other between his or her own, it is called “a clasping kiss.” A woman, however, only takes this kind of kiss from a man who has no moustache.
