snapdragon: [16] The herbalist John Gerard (no feminist, evidently) gave the reason why antirrhinums were called snapdragons: ‘The flowers [are] fashioned like a dragon’s mouth; from whence the women have taken the name Snapdragon’, Herbal 1597. The term was also used from the early 18th century for a party game which involved picking raisins out of a bowl of burning brandy and eating them while they were still alight – the allusion being of course to the dragon’s firebreathing habits.
snapdragon (n.)
garden plant, 1570s, from snap (n.) + dragon. So called from fancied resemblance of antirrhinum flowers to a dragon's mouth. As the name of a Christmas game of plucking raisins from burning brandy and eating them alight, from 1704.
