Origin Story
"Kkoturi" is the native Korean word for the pod that wraps the seeds of legumes such as soybeans and red beans. When the autumn beans were gathered and shelled, you had to pinch the pod where it would split and twist it open to free the beans inside. Because the pod was the very part you grabbed to get things started, "kkoturi" came to mean "the thread that begins a matter" — a clue or lead. Flip the same gesture around, though, and you find the nitpicker: someone who clamps onto a trivial detail and won't let go. Just as you seize and twist a bean pod, they grab a person's small fault and twist it into a problem. And so "kkoturi japda" — literally "to grab the pod" — settled into the meaning "to dredge up someone's weakness and pick a fight over it."
"Kkoturi" carries two faces at once: the positive "clue that starts something" and the negative "ammunition for nitpicking." It is striking that the very same act becomes a beginning or a quarrel depending on who does it, and with what intent.

Memory Hook
Picture fingers pinching a bean pod and twisting it open. That hand — grabbing something small and wringing it — is the nitpicker.
"Grab the pod to shell a bean, and it's a clue; grab it to fault a person, and it's a quibble."
