When you have a horrible case of diarrhoea but you just can't put down the latest
hunger games book, so you try to read while your insides
splurge out of you, usually getting
large amounts of excrement on the book in the process.
Man 1: Hey man, you sounded pretty
sick last
night.
Man 2: Yeah, but I managed to do some Diarrheading.
Man 1: Which book?
Man 2: The first Twilight book.
Man 1: Oh, good thinking. That book is
already full of shit, a little more wouldn't change it.
