foot bacon
When an individual begins pulling a small part of dry skin from their foot, and the actual strip of calloused skin becomes very long prior to removal. The resulting portion of tough/dry skin from one's foot is referred to as "foot bacon".
My feet were so dry after that long run on the beach... then I realized I was starving, so I dug my nails into the bottom of my foot and ripped off a nice healthy slice of foot bacon! It's like my own feet produce jerky.
