a.k.a. unfriend, defriend

To remove someone as a "friend" specifically on Facebook, for example, "I can't believe it, I just got defaced."

How do you "deface" someone on Facebook? It changes but usually you have to go to the person's profile, go all the way to the bottom of the left column, you should see a link that says "Remove From Friends." Note: It's considered a serious breach of a friendship to deface someone, and if you decide you want to be friends with this person again, you will have to send a new friend request.
