The canon of fandom.

Fanon is the collection concepts and ideas that are normally used in most fan fiction, but don't really existence in the real story's canon.

If a concept was used in the canon, it is only mention once in the entire series and is never mentioned again. Fan fiction writers will most likely instigate these concepts in their fics.
Some people think that fanon is phoney and stupid, but most fanon concepts are actually pretty good.

Something that the fans of a Fandom came up with that isn't Canon to the actual story or character. Not to be confused with Headcannon, which is a personal fanon that is usually only used by you or a small group.
"The fanon character is completely different from the Canon character!"
