Origin Story
Gojumangtae is a compound of two words. The first, goju, is an old term for the frame used to press and strain wine — also called gojo. Once the brew had fermented, it was filtered through this frame to draw off the clear liquor. Mangtae means a net bag for holding things; when straining, the yeasty mash was packed into this bag, set atop the goju, and pressed to squeeze the wine out. Naturally, the bag stayed soaked through with drink. Pressed again and again, sodden with wine and hanging limp — that very image looked just like a person so drunk they cannot hold themselves up. From this came gojumangtae: "a person as soused as the wine-soaked straining bag on a goju frame."
The companion phrase gondeure-mandeure is an ideophone for the wobbly, swaying look of a drunk, and the origin of its mandeure part has no settled explanation. Gojumangtae, by contrast, has a far clearer etymology, since it springs from a concrete object — a tool of wine-making.
