The Oxford English Dictionary has released its list of words of the year, which is topped by unfriend, a verb meaning "to remove someone as a 'friend' on a social networking site such as Facebook." Other honored words from politics are Ardi, birther, choice mom, death panel and teabagger. The latter word will now be used in headlines to refer to Tea Party Activists, now that the term has developed an accepted new meaning unrelated to male testicles.
