Pun on facebook. Another place where flakes can easily make passing commitments like the failed attempt to gather the world's biggest water fight. Most who signed up flaked on it. Also a place for fakes to claim strangers as friends.
Fakes use Flakebook to claim they have the most "friends", a lot of whom they don't even know and have never communicated with.

I know I agreed to meet up with her on Flakebook, but I have no intention to show up. I just wanted her to add me as a friend.

Someone who used to be a potential girlfriend/boyfriend, but no longer is.
Tim: Zack, is that your exgirlfriend?
Zack: No, she's an expotential. We never actually dated...
