A box that all spouses, parents, relatives, etc., have in their possession that that contain a multitude of items for them to bitch (complain) about on any given day.
1. Person 1: "Mom has been on my back all day about mowing the grass."

Person 2: "She must have looked through her bitch box today"

2. Person 1: "I don't want you going golfing today!"

Person 2: "Why? Did you add that to your bitch box too?"
