I don't mind bad writing as long as there's a good story behind it. Really, I don't.
But J.K. Rowling really pressed my buttons not ten seconds ago in Order of the Phoenix.
So here I am, sitting on my chair, bored, a headache coming on, reading the book, and then suddenly, without warning, near the top of page 242, is this (don't worry, there's no spoiler):
"We're not going to use magic?" Ron ejaculated loudly.
"Ejaculated." That's the word Rowling uses. A simple "said" works just fine here, or maybe a "shouted," or, hell, an "exclaimed," but no, she went with "ejaculated." I did a double-take, put the book down, and began writing this blog post.
Now I can't get certain images of Rupert Grint out of my mind.
