The UNfriend-zone 

It is when your friend finds a new piece of ass/interest and you soon find yourself becoming nonexistent to them. Its more common between a male and female friendship then a same sex friendships.

Megan: "Hey have you noticed since Brad started talking to Kelly he stopped talking to me."
Steve: "Sorry to say this but no matter how you look at it you are in The UNfriend-zone."

funfriending

Not Steve: "I funfriended the shit out out of Steve after he spammed my newsfeed about his new Jeep Wrangler. What a giant fucking douche."

Also Not Steve: "Funfriending is cathartic and fun!"

Preemptive unfriending 

When one deletes a friend from Facebook because he or she knows that the Facebook friend in question would eventually delete them instead. Preemptive unfriending thus robs the deleted Facebook friend of the joy of being able to delete them.

John: Why'd you delete Bec from you friend list?
Adam: I knew she'd eventually delete me so I wanted to take the satisfaction of unfriending for myself.
John: Ah, a preemptive unfriending.

Prefriend

Hybrid of "Pretend" and "Befriend"

When one is walking by them selves and lonely, To prefriend is to walk close enough to a group of people so that passers by assume you are with the group, but not so close as to make the group think you are following them.

Note: If one actually believes that they are with the group, they are not "Prefriending", they are just Delusional.

Usages:
To "Prefriend" to be with someone,
Or
One can be "Prefriending" to be with someone.

Person 1: "Hey look at Pete, I didn't know he was friends with the Jocks"
Person 2: "What?...Nah he's not, He's just "Prefriending" to be with them"
Person 1: "Pfft, What a loser"

Unfriend

The act of removing a friend from your facebook account.

Compulsive people prune their friend list periodically, removing people that they no longer have contact with. More often though, unfriending is only done when a particular friend's updates and self-promotions become so annoying that you can no longer stand hearing about them. Or you might unfriend someone when they piss you off, however, this is not very effective since the person who is unfriended is not notified that you unfriended them and you'd be better off to keep them as a friend and plot your revenge.

Dude, did you fucking unfriend me on facebook? I was looking for your email address and you're not in my friend list anymore. WTF?
