B-book
A B-book is the second book you get in a subject. It's like the a-book's annoying cousin who always shows up when you're trying to finish your work.
My math teacher said, 'You're doing the B-book now, so I hope you're ready for more trash talk.'
When I asked why we had a B-book, my friend said, 'Because the A-book was too good for us.'
The B-book is like the a-book's revenge, and it's here to make you cry.
