J.K. Rowling's first post-Harry Potter book The Casual Vacancy was released this weekend to (at best) mixed reviews. The one thing everyone agrees about: This is an Adult Novel with plenty of Dirty Bits. But how dirty is it? We've crunched the numbers.

Below, a list of some of the best dirty words, the frequency of their appearances in Rowling's book (at a length of around 166,000 words), and samples of the ways in which they're used. The upshot: this is definitely a Dirty Book — not quite Harry Potter fanfic-level dirty, but dirty enough for some 13-year-old to hide under his or her pillow for later.

Note: These are all direct quotes from the novel, but, in order to prevent spoiling the plot, we've replaced all character names with new, randomly-chosen names to hide their identities.
