To flirt with somebody overtime on Facebook because your both too shy to break the ice. Flirtbooking starts with clicking "like" on all of their post's, then comments on it to saying pictures of them are cute. Eventually you're drunk and message them at 2:46 in the morning.
1. The two people flirt and it appears on the FB newsfeed. YET, they don't seem to know they are flirting. Their friends just look at their spammed newsfeed with and expression that looks somethinglike this -_-
2. A person/people who looks at a book written by a person named Derek for flirting advice. That doesn't exist.
Using Facebook or another social networking site to flirt with old acquaintances or newly networked friends. Usually used as an icebreaker or foreplay before actually meeting up in person and doing the 'deed'.
As you are stalking your faux friend's new photo album on Facebook, paying close attention, you realize that two pictures in a row look peculiarly similar. So you press the left arrow to look at the first picture again. And then you press the right arrow to look at the second picture again. And then you continue to press left and right again and again so that it looks like your friend is moving. Flipping popcorn in his mouth. Crushing that beer can. Kicking rocks. Alas! Facebook Flipbook.
Dude. Did you catch that Facebook Flipbook of Nick? I kept pressing left and right, and it looked like his pants were disappearing and then reappearing.
