Happy National Unfriend Day.

Spell check says I have a misspelling in my headline here. That's because unfriend is more recent and bizarre as an English word than we think.

Can it really be so new? Doesn't it seem like it's been around forever? Doesn't it seem as if you've had extraneous friends -- lingering at the fringes of your subconscious, cluttering your chi, and generally weighing you down -- for ages now?

All those ex-coworkers, friends of friends, extended relatives and high-school vestiges relentlessly pummel you with their thoughts and developments, daring you to unfriend, and now Jimmy Kimmel is offering you the perfect excuse to cut them loose.

We didn't adequately consider the question of who is worthy of 'friend'ship, so now we're in the position of considering the resulting question: Who deserves to be unfriended? You probably already know.

These are the people you friended on a "what the hey" kind of day. You were feeling fine about it, and now you see their status updates and wonder what possessed you to accept that request. These are the people that you truly, madly, deeply do not care about. The people you forgot you friended -- or even knew.

I think it's ok to have some baseball-card friends. These are the friends to whom you have virtually no other connection other than Facebook and your shared past. But you really love that these people existed in your life, and you want to keep them in your collection. They get to stay.

Anyone who ever screwed you over in real life has to go. Anyone who actively annoys you with his or her status updates has to go. Anyone who never does anything on Facebook at all (except for my dad) has to go.

Maybe you are unfriending me right now.

Will you celebrate NUD?
