New Born word..

I found it in Reader's digest(May),a passage stated "newborn word".. and the word is UNFRIEND where a lot of people using it now especially in US.. example like unfriend in internet(removing your friend from a friend list) or whatsoever.. hahahaha the first respond after I read the passage, I was laughing and thought of my childhood when people don't want to friend with you.. they said, 'I don't wan to friend with you'(how childish!^^) and now we get easier to say that 'I unfriend you' and blah blah blah.. Human just want everything to be easy XD hahahaha.. you cannot find this word in any old dictionary, this is bizarre..
