"I'm totally going to unfriend him after what he did last night!" How many of us use that term "unfriend" on a daily basis? I've heard plenty of friends say this after many nights out in downtown Athens. Apparently, the term has found its way into everyday conversation so much that it has been chosen as the Oxford Word of the Year for 2009. This blog lists other social networking terms that almost made the cut for the current year. Senior lexicographer for Oxford's dictionary program explains, "Unfriend has real lex-appeal." Love it.
