Apparently the word 'unfriend' is the new word to be added to the Oxford English dictionary. One of the other options was 'funemployment' which means "to use one's unemployment to pursue one's interests and hobbies" haha.
It's funny that I found out about this the same time that I decided to quit Facebook. It was really beginning to annoy me in every respect, and no Facebook, I won't miss anyone because anyone who is a real friend I can email or see in life (and our conversation wouldn't be up for everyone to see!).
I unfriend you, Facebook!
