Any competent English teacher would tell us that rain symbolizes change; kissing in the rain, therefore, symbolizes a change in the relationship between the characters.
A psychologist would probably tell us that being wet symbolizes vulnerability - a state in which we allow our normal inhibitions to lapse.
Cinematographers would probably tell us that this has to do with good film-making - precipitation is inherently dynamic and dramatic.
Obviously, there IS a reason ... how else to explain the number of enormously romantic movie kisses that occur in the damp? The following is not a comprehensive list, but does include some of my all-time favorites.
