Question: What does "du kaya mischna" mean? Ida says it when falling asleep during the Christmas episode with Francis.
Answer: Right, complete nonsense. Du, obvious pain prefix for two, Kaya is drugs in Jamaica and a fruit, coconut thing in Asia, and Mishna, spelled multiple ways, are certain types of studies in Hebrew.
Answer: It is made up - although it is implied she is Croatian, she never mentions it herself.
