Moon door is a phrase that means "get rid of." It is used by people who don't want to see a certain person anymore.
The term originates from the Vale of Arryn moon door featured in Game of Thrones. The door is used to throw people, usually condemned men, to their deaths several hundred feet below. The phrase has become popular when wanting to break up with somebody or not see a friend anymore. It can also be used as a noun as in "give your gf the moon door already."
