A social get-together that involved the auctioning off of boxed lunches prepared by the women. A potential sweetheart might let her man of choice know how she had decorated the box she prepared so that he would try harder to be the one to successfully buy it at auction. This was a way for young women to show off their meal-making skills. He who bought the lunch would share the meal with the one who prepared it.

My grandparents met this way; my grandmother was Amish and my Scottish grandfather paid a HUGE price to purchase her box lunch.
Violet decorated her box lunch with daisies so that Milton would know which one to bid on at the box social.

The opposite of a sausage party. A gathering of people in which the number of females, preferably hot ones, is significantly higher than the number of males. Hence, a social event with a lot of box.
"So what did you do for Doug's birthday?"
"We went to 35 Beaver St. It was a total box social!"
