Unfriend - New Oxford American Dictionary’s word of the year for 2009. It’s a verb meaning “To remove someone as a ‘friend’ on a social networking site such as Facebook.”
Ah, Facebook. It’s the entire Internet for some. A stalker’s paradise for others. In general, it is a good way to maintain online contacts, or “friends” in the Facebook vernacular. Often, Facebook friends are really friends, and almost as often they aren’t. But either way, is a Facebook friend just as important as a friend in real life?
