duster
1. The buttocks. Dad will spank your duster if he finds out you were playing so close to the street.
2. A knee-length sweater or coat. It was colder out than I thought it would be, so I threw my duster on before leaving the house.
ear-duster
Someone who is apt to gossip. Janet's definitely an ear-duster—if you tell her you're pregnant, everyone will know by noon.
