To facebook a fat chick and start looking at her most recent and probably fattest pictures. Then you proceed to go back in time and view her earlier pictures. In most cases you will watch her get younger and skinnier.
Adam found a fat chick on facebook. Since fat chicks have no use at all to Adam, he decided to amuse himself at her expense by Benjamin Buttoning the bitch. Turns out the bitch was ugly even at a lower weight.
