FBF 

Abbreviation for "facebook friend".

Similar to BFF, only 1000x less personal.

Girl 1: "So I was talking to my cousin's roommate's little brother the other day, and..."

Girl 2: "Hey, I know him!"

Girl 1: "Really? How?"

Girl 2: "We're FBFs. Duh."

FBF 

Face blunt Friday. a college tradition to start of the official weekend. after a hard week's work of classes, homework, and exams the best way to relax is to smoke a blunt to your face with your best friends.

FBF usually starts right after classes so you have something to do to fill the time void between end of classes and the start of parties. you're high will last until and after it's time to party making for an even better Friday night.

1. dude all-time record for FBF. 15 people... that's 15 blunts and half ounce of weed all smoked at once! i love FBF!

2. i was so fucked after smoking that blunt to my face. it was so worth it. can't wait for next week's FBF!

FBF 

Facebook friend. Like BFF, but in the social network world. Requires official confirmation of friendship. Conversely, can be unfriended with a simple click of the mouse (no falling out needed).

Hey, why won't you add me as your FBF?
