California slang, circa 1946

I'm once again transcribing letters sent to Mom. One of her friends (temporarily living in California) mentions local slang, circa spring 1946. Lush means luscious, as in "that coat is lush." Icky means, well, icky--but apparently that wasn't slang familiar to a young lady from the Bronx. This was interesting enough to merit a paragraph in a one-page letter. Who knew?
