I saw it then as being a variation of the traditional American "shotgun wedding." It was a kind of Sadie Hawkins day.
"Sadie Hawkins Day was named for a cartoon character developed by Al Capp for his Li'l Abner comic strip. Sadie Hawkins was so ugly that her father, Mayor of Dog Patch, U.S.A., feared he would never marry her off. In desperation, he decreed a Sadie Hawkins Day. All unmarried men in Dogpatch would get a ten minute head start before Sadie and the other unmarried women began running after them. The man each woman caught would end up in front of Marryin' Sam for a shotgun wedding."
