BFFFRN 

Some person on Facebook who has been leaving a lot of comments on your posts. However this is a person who you never hang out with in real life. Therefore he/she is a Best Facebook Friend For Right Now.

Yo, whose this girl blowing you up on Facebook recently?

I just met her. She's my BFFFRN.

The sickening feeling you get whenever you see two Bffs interacting with each other in a obnoxious way.

1. Hey did you see those two best friends try out together on American idol last night. They made me want to Bffarf.
