A person who feasts; someone who eats and drinks lavishly or participates in a grand celebration meal.
From 'feast' (a grand meal) plus the agent suffix '-er,' which creates nouns meaning 'one who does' something. 'Feast' itself likely comes from Latin 'festum' (festival).
In medieval literature, 'feasters' gathered in great halls—and the grandeur of a feast was so important that special servants, called 'feasters,' were trained just to manage the eating and drinking rituals!
