A nick name for "Facebook" derived from users reconnecting with each other after years of no communication and seeing that each other has gained substantial weight.
Bryce- "Dude I just met that cute chick Kelsey at the partythe other day, next thing you know I get fastbooked! Came home that same night to a friend request."
Noah- "Mad fastbooking indeed my man, wasn't that party upstairs?!"
The other day, I really wanted to fart. I tried so many times, I squeezed, grunted, and even screamed, but nothing would come out! I was so fartbroken.
the most convenient form of communication for fratstars used to keep up with brothers and of course the sorostitues from the night before. also, a great way to keep up with other people's business and to know who's hooking up with who.
