In fandom, refers to events that occur outside the scope of a particular storyline. These events may or may not be referred back to later in the story. Oftentimes, an excuse given for failure of the story to conclusively wrap up dangling plot threads, or explain away plot holes and continuity errors. The term originated in Smallville fandom.
Although Lois Lane and Kara Kent had not met on screen in the TV show Smallville, Lois claimed that they were good friends. The development of that friendship was said to have occurred in Offscreenville.
