Red wedding means disaster. It is a slang term used to describe an event that has turned into a disaster.
The term originates from Game of Thrones where the wedding between Edmure Tully and Roslin Frey turned from a happy occasion into a bloody massacre. The phrase can also describe a person who has become a disaster, or mess, as well.
