|1.||Granny panty hoarder|
The female act of washing your granny panties because you are afraid to dispose of them unwashed, for fear that they will be found in the trash and traced back to you. But then you wear them "one last time" because you just washed them.
Susan was so ashamed for anyone to see her granny panties, she refused to throw them out. She was a granny panty hoarder.
