Definition: "Yarder" refers to the size of a rolloff or dumpster. Specifically, it refers to the number of cubic yards contained within the container.
Rolloffs typically are 10, 20, 30, or 40 yarders.
Thus, a 20 cubic yard dumpster would be called a "twenty yarder."
Examples:
He rented a giant-sized forty-yarder (dumpster) before demolishing the shed behind his house.
