What Do You Call That?

My brother was reading a book of mine the other day and he began quizzing me on some things  such as ferrule and keeper. One he mentioned sounded very familiar. I discovered that I had blogged about it several years ago when I had first read the same book. I decided it needed an entry in my glossary along with a rhyming word that also a little odd. Do you know your tittles from your nittles?

(And if you're wondering: ferrule is the metal band that holds the eraser on a pencil and keeper is that loop on a belt that holds the end in place after it goes through the buckle.)
