In Hawaiian, the word X means “to bake in the ground” – it can also be used to refer to the Hawaiian food (usually containing pork or turkey) cooked in this manner that is often served at feasts and has since become a major tourist attraction.
X is not to be confused with the very similar-sounding but completely unrelated Y, which is a coffee liqueur made from rum, Arabica coffee, and sugar. Y serves as a key ingredient in several cocktails, some more prominent than others.
