Ad Fundum

Ad fundum (Latin for "to the bottom") is a drinking term primarily used in student societies and fraternities, signifying that the entire contents of a glass or drinking vessel must be consumed in one continuous gulp, draining it completely. The phrase is often used as a command or challenge. While the precise origins are unclear, the practice is likely rooted in historical customs of toasting and demonstrating camaraderie (or asserting dominance) within social groups. The use of ad fundum is most commonly associated with beer and other alcoholic beverages, though the term can technically apply to any drink.
