Die Erklärung, warum Kiki in dieser Version Nicky genannt wird (Zitat):
"to make a kiki" is a vulgar slang term used by males (usually teenaged boys) meaning "having sex with". To make things worse, translating "Kiki's Delivery Service" literally into Spanish would come out implying this is a travelling brothel!! (Poor Miyazaki. He just can't win in Spanish....)
Note: this is *European* Spanish slang. According to my
wife and our other Mexican-American bilingual friends, no one has ever heard of "kiki" as a slang term in Mexican Spanish.
