The standard defines "undefined behavior" as "behavior for which this
document [the standard] imposes no requirements". I recommend not using
that particular phrase with a different meaning.
Certainly relying on behavior that isn't defined either by the standard,
by any applicable secondary standard, or by the implementation is a bad
idea.
