subs. (American).A very old name for a mixture of rum and spruce beer, being quoted by Grose in 1785 as an American beverage. The last two syllables of the word are thought to be derived from the French bagasse, the refuse of the sugar cane. This view would seem to be supported by the fact that rum is itself a product of the sugar cane.
