A type of romantic short story or fanfiction, similar to the slasher in how it falls into one particular genre that is somewhat specific. A fluff story has two characters who expresss their feelings towards eachover and eventually snuggle and/or cuddle (Non-sexually), usually to the sunset or during a starry night. It has very little focus on story and just contains alot of cuteness.
Comes from "fluff"; a story with no real story.
