When you cannot fall asleep so you turn to facebook to lull you to sleep, therefore cutting down on the amount of sleep you would have gotten had you not went on facebook in the first place

Brandon: ya I couldn't fall asleep last night and had to use the Facebook Lullaby
Mark: (knowing look) ahhh...
