Maundy Thursday

The dialect name for Maundy Thursday, Grie(ner)-Durmerschdawg (Green Thursday, literally), is in very large part responsible for the basic lore that attaches to this day: One must eat something green on this day. […] Failure to eat something green on Maundy Thursday had dire consequences, according to the folk mind: One would get the itch, one would become lousy, or as a York County informant put it, "Mer iss s gans yawr uff em aisel." (One will be a mule all year long.)
