Said of machines delivered without an operating system (compare {bare metal}). "We ordered 50 systems, but they all arrived nude, so we had to spend an extra weekend with the installation disks." This usage is a recent innovation reflecting the fact that most IBM-PC clones are now delivered with an operating system pre-installed at the factory. Other kinds of hardware are still normally delivered without OS, so this term is particular to PC support groups.
