BUFF, a dull yellow leather originally made from the skin of the buffalo (Fr. bugle, a buffalo), now also from the skins of other animals; used for making the military buff-coat or jerkin. The East Kent Regiment and the 2nd battalion Seaforth High landers are called the "Buffs" and the "Ross-shire Buffs" respec tively, from the yellow or buff-colour of their facings. The term is commonly used now of the colour alone.
