A name given to a character by fan communities. It is sometimes possible to read an entire forum about a show and never see a direct reference to the character's scripted name. A natural result if the producers take too long in providing a character with an official name. Note that these aren't specifically limited to characters. Common sets, props, and special effects can also earn nicknames from the fans. Even (parts of) the series itself can be referred to with a nickname. Works suffering from Recycled Title syndrome are very common to have a fan nickname to avoid confusion.
