1. Inform
The troper described the trope, in which a type of Fan Fiction is produced.
2. Substance
The fanfic type consists of short, numbered prompts, sometimes suggested by other authors. Usually of Drabble length, but sometimes as short as one sentence.
3. Guide
The prompts themselves are usually the most general nouns as possible, such as "love", "kiss" "burn", and are not really connected to each other.
4. Love
Since Most Fanfic Writers Are Girls, the prompts usually describe various aspects of the relationship of two characters within a fandom.
5. Clash
Sometimes several writers will share the same set of prompts and compete with each other, or simply apply the prompts to all their favorite fandoms.
