look up any word, like the eiffel tower:
The downy matter that rests under one's bed and is composed of bed sheet fibers, hair, dust, and any sort of textile debris. Sluts are too busy working that they barely have the time to clean under their beds, hence the name.
This morning I decided to clean up my house and there was sluts' fluff under every piece of furniture.
