A time honored tradition that occurs upon the years first sight of snow in which you may ask any female you encounter to show her breasts. It is widely thought to have originated during the early American colonial period somewhere within the New England colonies. The term was formed by combining the words "Snow" and "Tits".
Walking down the street I realized that it had begun to snow for the first time this year; I excitedly proclaimed, "SNITS !" to the first group of women that I could see, to which they promptly lifted their shirts showing me their breasts and then continued on their way.
