Jack in the green

English Jack in the Green Noun Jacks in the green en historical A person who wore a pyramidal or conical wicker or wooden framework decorated with foliage, as part of May Day processions in England. Mr Merdle took down a countess who was secluded somewhere in the core of an immense dress, to which she was in the proportion of the heart to the overgrown cabbage. If so low a simile may be admitted, the dress went down the staircase like a richly brocaded Jack in the Green, and nobody knew what sort of small person carried it.
