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.

The Granny Pantie Waddle is when a very large woman, likely over 400# (28 stone), shakes her rear end for a show or performance. Women this large have much fat on the rear end that shakes like a magnitude 9 earthquake. The name is derived from the fact that women this large are relegated to wearing granny panties due to their size and for the flexibility that such undergarments offer.
