The defining moment when on facebook that you feel like facebook came alive and every one of your friends that are online are actually participating instead of just viewing pics and laughing at inside jokes, but then the scocializing stops in a way that feels like if facebook died.
This is rarely experienced by pretty girls who go to middle school, high school, college, and bars to hook up. This is due to the fact that it is uncommon for these people to not have a minimum of 20 friends online at any given time and also since these are the people who write the inside jokes and post the above mentioned picture.
Facebook went from alive to really slow at 3 am? Ah, yes. The F- Surge. Have you tried adding more chicks on your account?
