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 something like this -_-
2. A person/people who looks at a book written by a person named Derek for flirting advice. That doesn't exist.
*after a series of flirtiful events*
Derek:Why don't you guys just make babies.
Guy:Where did you come up with this???
^^^^^these people would be the flirtbook fools.
Derek: oh man i have to make a name to express myself. oh I got it.
