Facebook Vampire
a person who thinks Facebook is more important than sleeping, even when it's 2 AM and they're still wide awake.
At 2 AM I was still on Facebook because I thought my crush was going to message me.
I had a dream about Facebook and I woke up at 2 AM to check it.
I'm so obsessed with Facebook that I checked it at 2 AM and forgot I had to go to school.
