A Fix Fic is a fanfiction for which the author's main purpose is to change or 'fix' something in canon. They often address elements from large story arcs, or recent episodes, and usually change or alter the events depicted to match the author's desires. Fix Fics come in two varieties. Either they can be an Alternate Universe Fic that ignores the unwanted elements and replace them with something better. Or they can be an elaborate explanation in story form that gives a whole new spin to the latest episode.
