Unfriend me?

The New Oxford American Dictionary has named "unfriend" - which means deleting a 'friend' on a social networking site such as Facebook - as its 2009 Word of the Year.

There were times when unfriending was done manually. Now it's all electronics.

I'll unfriend you
You'll unfriend me
We'll be one unhappy unfamily

Oh boy... and don't tweet me too, please!
