When a group of people hook up in a shed outside of a house, usually at a party or just for fun. The group consists of four or more people, usually good friends who don't mind performing sexual activities in the presence of their close friends. The next day these people are called the "shed group"
Omg did you hear so and so hooked up last night? In a shed... whatta shed group.
