(Scotland) Fluff, particularly from a textile source such as cotton or wool.
But I found how I could read in the bedroom and not lie on the bed. It was a wee place down between my bed and the wall where the door was. The bed was pressed against the wall but ye could just squash down and under. My da kept all suitcases under my bed but I shifted them the gether and it was easy to squash in. But when I came out it was all fluff and oose stuff down my pyjamas. My maw was shouting. Oh Kieron it is filfy it is just filfy.
