"Younguns, hain't I been mommucked this day!" is a distinctive Ocracoke expression. For all of you off-islanders, to mommuck means to harass. The expression above generally indicates that you've had a rough day. Maybe your grass cutter wouldn't start, the neighbor's dog tore up your garden, you burned the meatloaf in the oven, and lightning knocked out your telephone service.
Mommuck can also be used to inidicate that one person harrassed or beat up on another. Or it can be used to describe conditions in Pamlico Sound, as in "I was mommucked right, out there fishing my crab pots this morning," meaning that the water was choppy & rough.
If this has been a difficult week in the office, just stand up and announce to your co-workers, "Younguns, hain't I been mommucked this day!" Maybe it will remind you of Ocracoke, and help you feel a little better, even if you do get a few puzzled looks.
