Usage

What does fluff mean? Fluff is a light, soft mass, such as cotton or a cloud, as in After I shaved my head, the hair that grew back was soft, like fluff. To fluff something means to shake or puff out something, as with pillows. When you fluff your hair, you might shake it out a bit so that it puffs up and looks fluffy. Fluff can also describe something that is of little importance, such as a novel that someone deems fun but not at all serious. Fluff is also a mistake, especially a situation in which an actor forgets their lines. To fluff is to make such a mistake, as in Valerie fluffed her lines during the first scene, but she quickly recovered. Example: When Grace and I were stuffing the pillows we had made, we had fluff flying all over the living room.

Explanation

Fluff is a soft, light puffy or feathery material. Your pet angora rabbit is covered in fluff, and when you blow the down off a dandelion, you can call that fluff too. A department store window designer might use white cotton fluff as snow in his holiday display, and a bored dog might pull the fluff out of every pillow in the house while you're at work. The word fluff is also a verb meaning "to shake or ruffle until something looks fuller." It's also a great way to describe something meaningless or frivolous: "I had high hopes for the newspaper article, but it was just fluff."
