VUVUZELA, overleveraged, quantitative easing, staycation,
bargainous, social media, defriend, tweetup, bromance, buzzkill,
cheeseball, chillax, frenemy, interweb and wardrobe malfunction.
According to Reuters, these are among the words welcomed into
the Oxford Dictionary of English in its latest edition.
According to a certain view, their "in the dictionary" status
makes them now "real words". I don't share that view (the set of
legitimate words is bigger than any dictionary, and anyway which
dictionary and why?)  But I'm not some accept-it-all softie,
either, and I have to say I think a few of these are odd
additions.  Vuvuzela is a real word for a real thing, borrowed
into English and likely to stay, especially in South African
English, for a good long run. "Overleveraged" and "quantitative
easing" are borrowed too, but only from specialist usage into
general knowledge, alas.  (Does anyone really think
"overleveraged" wasn't a word before this week, by the way? My
Microsoft spellchecker even recognises it.)
