Gin marriage laws were laws passed in several American states in the 1930s that required waiting periods of several days between getting a marriage license and marrying. They were passed as part of a Prohibition-era moral panic over the idea of couples getting married while drunk.
In 1927, The Pittsburgh Press said, "It was believed that a three-day cooling off would temper the ardor of unruly impetuous maids and swains."[1]
