A room in which the twentieth century family sits down to have a nice meal together, usually dinner or supper for you southerners. Commonly, now adays, the dining room consists of computers, toys, boxes, last years christmas fruit cake and maybe even a book case.
Friend 1 talking about other friend: Dude, we hooked up last night, she hated it and now she doesn't want to come sit with us anymore!
Friend 2: That's why you should stay away from In-room dining!
