means A Hawaiian feast, usually outdoors, built around a whole roasted pig and shared communally with music, dancing, and tables of side dishes.

from Named after the Hawaiian word for taro leaf — 'lau' or 'luau' — which was traditionally cooked with coconut cream and used in a classic island dish served at these gatherings. Over time the dish's name stretched to cover the whole feast around it, so the word you're eating with now once just meant the greens on the side.
