Fanfic filling the space between scenes (in a TV series or movie). Writing or describing something that hasn't been sawn.
- You should write a gapfiller about what happens after Brian and Justin have that conversation in the loft.
- Man, everybody knows they had sex.
- Yeah, but I'd like to read that scene. We haven't seen it!!
