to continue with that --
Angst: Genre that is opposite of Fluff, in which you might find terrible happenings like character death, rape, etc.
PWP: Porn without plot, which speaks for itself.
One-shot: Fanfiction that is meant to be only one chapter long.
AU: Alternate-Universe. Stories like this take place in a setting that's different from canon, like, for example, taking the characters of Naruto and putting them in high school.
WIP: Work-in-Progress. The fanfic isn't completed yet.
On Hiatus: Author is taking a break from the story for an indefinite amount of time.
