A harold (HRLD) is a volumetric measure of Birthday cake. . It is equal to 90 cubic inches.
Joanne ordered a quarter "Harold" of cake at the local restaurant. Bob went for the "full Harold" and all were amazed! Matthew was able to eat a half Harold of cake and was satisfied. A 10 Harold cake is a very large cake!
