A tongue-in-cheek name for rust removal duty (ferrous oxide being the precursor to rust on steel objects), especially on Navy ships, playing on the vivid contrast between the tedious and highly unpleasant nature of the duty, involving the use of wire brushes and toxic chemicals often under a blazing sun, compared to the delightful, carefree leisure tableau depicted by the three teen protagonists of the 1986 Matthew Broderick film "Ferris Bueller's Day Off."
Chief Petty Officer: It's your lucky day, sailor -- two weeks of Ferrous Oxide's Day Off starting at eight bells.
Sailor: Aye-aye, Chief.
Chief Petty Officer: And don't ask my daughter out again.

An off day, also referred to as a bad day (and not to be confused with a day off), is a day where you're...not yourself. Maybe you've been a bit down on your luck as of late. Maybe your parents are reminiscing to their friends about that awful/embarrassing thing you did when you were four years old that you've been trying to forget for at least a decade or two. Whatever it is, you're probably going to be very sullen until your life starts showing improvement.
My mate suffers from depression, and he has both good days and off days. One day he'll be just fine -- maybe even a little cheerful if something good has happened -- and then the next day, he'll be very sullen and down in the dumps; when this happens, there's absolutely nothing that can make the metaphorical rain cloud above his head disappear. You just have to wait until the off day runs its course.
