Origin Story
The "juk" in gonjuk is indeed the porridge (粥) we all know, but the "gon" in front is the surprise. This "gon" is an adjectival form of golhda, meaning to rot soft inside, or to ail quietly and waste away. So gonjuk originally meant "spoiled, gone-soft porridge" — gruel boiled too long or gone off until it lost all form and turned to mush. From there the meaning branched two ways. In one, by analogy with that collapse of form, badly waterlogged rice or ground turned to slop after rain came to be called gonjuk. In the other, the sense rose to the abstract: an affair fallen into hopeless, jumbled disorder is said to have "become gonjuk." Beyond even that, a person so slack from drink or exhaustion that they cannot hold themselves up is described as being "worn to gonjuk." A single bowl of formless, spoiled porridge became the metaphor for everything that has collapsed into a mess.
With a single bowl of porridge gone shapeless and soft, we picture sodden ground, a botched affair, and an exhausted body all at once. The most concrete shape of a food became the widest of metaphors.
