The account you made before you made your permanent Facebook account; the one you used to get a feel of Facebook and to check out people profiles in hopes of being able to view them by meeting the criteria of having an account. Usually named after your alias and does not contain any photos.
Your girlfriend: (casually browsing through your account): It says here under the People You Might Know category that you might know Joe Snuffy. Who's that?

You: Oh, that was just my Testbook. I used it to check out people's profiles before I actually committed to Facebook.

Your girlfriend: Wow, did you "Testbook" me before we met?

You: I plead the Fizzif, bitch!
