A female member of a separated marriage in which reconciliation is not an option, but for which a divorce has not yet been finalized.
When we were engaged to be married, she was my fiancée; now that we're engaged to be divorced, she's my deancée.

This weekend I've got to go over to my deancée's place and pick up the rest of my shit.
