Regarding our recent story on the term “unfriend” being named the Oxford American Dictionary’s word of the year, we heard from a number of people who say they’ve never heard anyone say “unfriend,” but rather, they hear and use “defriend” instead — as in, “I defriended her on Facebook because she was always sending me stupid quizzes.” Ammon Shea from Oxford University Press was gracious enough to talk to us again to clear up this “unfriend” versus “defriend” issue.
