Facebook Quiet Hours
Facebook Quiet Hours are the time when the site is so quiet you can hear your own brain screaming because no one else is stupid enough to be on Facebook at 3 in the morning.
Status: 'I just posted a wall-to-wall status and no one read it. I'm dying.'
Tweet: 'My friend is online at 3 AM. I think they're trying to kill me.'
DM: 'Why are you still here? It's 3:42 AM and I just posted a Farmville update.'
