Removing the first slice of bread in a loaf to take the fresher one underneath it. Usually the second-slicer neglects to throw out the rejected first slice, instead choosing to crumple it back into the packet. This eventually leads to third- and fourth-slicing, until basically the whole top half of the loaf is stale. Also applies to: biscuits.
"Why are the first three slices of this loaf all crumpled and stale?"
"Urgh. That would be due to the second-slicing."
