"Right side up" refers to an object that is in its proper or correct orientation. For example, if a book is upside down, it is not right side up, but if you turn it over, it becomes right side up. This phrase can be used to describe anything that is supposed to be oriented a certain way, such as a picture or a toy. It is important to make sure things are right side up so that they can be used properly and look their best.
