FaceBook Friend (n)

1) The facebook version of a "BFF.";

2) A person that you are friendly with and/or think is cool but don't necessarily hang out or know.
a. Co-worker: "Don't worry we're FBFs so I'm sure we'll keep in touch after I leave."
b. New acquaintance: "Hey, it was really good meeting/you hanging out last night. Let's be FBFs and get together soon."
c. You: "I wouldn't say were like friend-friends...we're just FBFs."

FBF (Fat Bitch Friday):

The only time it is acceptable to drunkenly go home with, or allow a drunken friend go home with, a fat chick. It is only acceptable on a Friday after a drunken night of striking out with decent chicks and only acceptable between 11pm and 3 am on said Friday night/early Sat morning. Failure of abiding by these rules is a breach on man code and the violator willfully subjugates himself to a minimum of 3 1/2 weeks of being ridiculed and may also be kicked in the balls or have his man card taken away until he proves himself worthy once more to hold it.
Dude, it's not FBF, stop talking to that fat skank!

Fuckin' Best Friend
Similar to BFF but without the girly connotation. What you'd call your best buddy who you know will stick with you through thick and thin. You look forward to hanging out and doing shit with them and there's always better things to come. Even when they've gone someplace far away it still feels like they're there with you. They're not just your best friend, they're your fuckin' best friend.
AT: Hahaha that was pretty crazy. Gotta run now, have a good one FBF
MY: See ya later, my FBF
