I literally screamed "ohhhhhhhhhhh" but I wasn't in theater. I was watching this movie first time in my room at 2 am. So when I went "ohhhhhhhhh", it woke up my parents and they send me to couch to sleep.
I'd never thought of the Voynich manuscript in this way before, but it does make more sense than most of the "mainstream" explanations. It would not be the first time that a group of women created a language for their protection, either.
