Since when is Oxford an Expert Anyway?

So, Oxford Dictionary announced its Word of the Year today, and the honor goes to "unfriend." With competition like "hashtag," paywall," "zombie bank," "choice mom," "teabagger" (not the good kind), and "brown state," we understand how the winner was chosen. But then you get to the last word on the list of contenders. How was "tramp stamp" so obviously snubbed?! We want a revote! What a travesty!
