Read Only Memory derivative. Office speak (IT slang) for people who will never "get it". Like a ROM chip you can't write to, they cannot have new thoughts, they only spew back what has been programmed into them. Unable to write to their brain.
Bob: I need more memory, but I can't afford a hard drive right now so I am just gonna download a bunch of my files to a CD.
Jeff: He is such a ROM.
