Oh, I like this. When your boss talks to his boss about the meeting, his boss doesn't have any specifics about him, which looks way scarier. If you brought up the manager, it'll more likely wind up looking like something manageable.
"Managing up" doesn't just involve sucking up. Your knife may be smaller than your boss's, but it's still a knife -- a lot of complaints about the modern workplace would disappear if more subordinates learned to use the tools at their disposal.
