You guys asked for it, so here it is!
This book is for fairly advanced speakers who want to learn what most French people actually say on a daily basis, because a lot of the more informal expressions and vocabulary you learn in school and on the internet is really outdated and sounds kind of goofy in real life.
I give you most of the slang/informal French I hear everyday as an American living in Paris - even the swear words ;)
