6 July 2015 is International Kissing Day or World Kiss Day. The idea behind the International Kissing Day is that many people may have forgotten the simple pleasures associated with kissing for kissing's sake, as opposed to kissing as mere social formality or prelude to other activities. Kissing can be an enjoyable experience in and of itself. It is an expression and experience of intimacy. International Kissing Day is not as commercialized as Valentine's Day.
A kiss is the act of pressing one's lips against the lips or other body parts of another. Cultural connotations of kissing vary widely. A kiss may be used to express sentiments of love, passion, affection, respect, greeting, friendship, and good luck, among many others. The word came from Old English cyssan "to kiss", in turn from coss "a kiss". The act of kissing has become a common expression of affection among many cultures worldwide. (From: Wikipedia)
