Fluffy means soft and light, with air caught in it. A duckling, a towel straight out of the dryer, the foam on a cappuccino, a kitten's tail.
Two pictures share the word. One is texture: covered in soft, loose fibres or fur — a fluffy jumper, fluffy hair after a wash. The other belongs to the kitchen: full of air and not dense — fluffy pancakes, fluffy mashed potato, fluffy rice where every grain stands apart. Behind it is the noun fluff, the grey stuff in a coat pocket and under the bed. Said of ideas or writing, fluffy is an insult: sweet, vague, nothing solid inside.

Fluffy is fluff with -y stuck on the end, the way dust gives dusty and mud gives muddy. German built its word for the same softness in much the same way: flauschig.
