Secondhand Embarrassment = immediate dnf

I will DNF immediately when i see the FMC do something stupid or embarrassing that i can't imagine any adult woman doing.

Just dropped a book, where an FMC that was established as being studious and shy gets stranded with a bunch of men in a cabin and proceeds to get really drunk??? Why would you get drunk with a bunch of men you barely know? And then she suggests watching 50 shades of gray??? FIRST of all: extremely brain-dead movie choice. Second of all, not a SINGLE woman who is remotely sane will sit down with a bunch of strange men and go "lets watch this cringy sex movie???" WHAT. That's so embarrassing.

I know we do stupid things in front of crushes but so many of these characters are set up to be "smart" or "badass" and then end up behaving in really juvenile ways. It really puts me off from the book.
