It's not an idiotic name, but you _clearly_ don't have any embedded
experience. :-)

It's from the embedded world and means application code that runs
directly on the hardware without any operating system between the
code and the hardware.

In the same way, it was extended to mean operating systems that run
directly on the hardware instead of under some hypervisor.

If you ever see a reference to an operating system running on
"bare metal" while the operating system is in fact running under
a hypervisor and not directly on the hardware, then that's the
marketing people playing idiotic word games to try and make their
solution appear to be something that it is not. Such people can
(and should) be ignored.
