The wierd plastic aparatus you often find stuck in your delivery pizza. This is used to prevent the box from squishing it and/or turning it to pizza mush before it gets to you.

The part of the pizza that's left over after someone's eaten the part with all the toppings on it.
Bob didn't like the crust, so he left all his pizza bones on his plate.

The outer crusts of a pizza.
All that's left in the box are the pizza bones.

n. - the outermost (usually overcooked) untopped edge of the pizza by which most of us hold each slice while consuming.

The edge of the pizza, which has no toppings, the "crust". Often left over, which most normal people simply refer to as crust, but Victor calls "bone" as in "pizza bones".
Mike said "Dude, don't put your crust back in the box, there are pieces left in there, that's gross" and Victor from then on, left his pizza bone on his plate, like civilized people do.
