There is no true definition. The word is only used by the master of masters. Although the word phrase has lots its translation and true meaning during the time of the medieval ages, some believe that it means to know "what is best". If someone were to make a wise choice, then another party would exclaim that this person "knew his/her goods" in that specific area.

When someone who you have met on several previous occasions acts like they don't know you when they see you in a different setting.
