  • Drabble: a very short oneshot, usually around 200 words.
  • Oneshot: a fanfic captured in, well, one shot.
  • AU: a fanfic set in an alternate universe.
  • Beta: someone else, like an editor, who goes over your fic.
  • Fluff: a fic where there's no angst or "real" plot. Usually short and sweet.
