The Karate Kid Part II (1986)

Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.

Chozen: You insult my honor again, I'll kill you.

Trivia: When Daniel and Miyagi are picked up at the airport by Chosen, the radio is switched a few times before landing on a specific station. The song the radio is playing is the same song played at the country club in Karate Kid I where Johnny kisses Ali.

Question: When Chozen, while bullying Daniel, takes the latter's handheld drum (which Chozen mockingly called a "baby rattle") and calls the latter a baby, Kumiko, sticking up for Daniel, fiercely says a phrase in Japanese (or Ryukyuan) to Chozen. What exactly does Kumiko say, and what does it mean? (00:57:50)
