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.
