The act of using facebook as an excuse to hit on someone. Can be used with true information and false, see example below.
A guy is telling his friend his latest face up line:

Guy 1: 'Hey, are we facebook friends? I think I recognize you from my news feed.'

Guy 2: 'Did it work?'

Guy 1: 'Yeah it worked. That's a classic face up line right there.'
