Yet again the Belated Word of the Week is

Crusily: covered with crosslets, or strewn with crosses. Apparently a medieval heraldic term, used to describe such-and-such lord's coat of arms. So "gules crusily" would mean a red shield covered with crosses. A "gules crusily and fess dancetty" would mean a red shield with crosses and a gold zigzag stripe. How cool is that?
