It probably started as box-standard — the normal one that comes in a box — and then the first half got mixed up, perhaps with bog meaning toilet, or bog meaning wet wild land. Some people say BOG stands for “British or German.” That is a story people like; it is probably not the real history, because box-standard is older.
