When one says "put the leftover pizza in the fridge", I imagine that the leftover pizza might mean one or a few slices of pizza that are decent enough for a person to eat as a meal or a snack.
However, say, I ate almost all the pizza and there were a few small pieces left. These pieces were bigger than crumbs but much smaller than a slice of pizza. Also, they came from the rear or edge of the pizza (is it correct to say the rear or edge of the pizza?) which were a bit burned and I don't eat the burned part of a pizza. See the picture below.
We can put these small pieces in the fridge but most people will dump them in the garbage.
Can we say "I dumped the leftover pizza in the garbage"?
Does it cause confusion to say that?
