Jimmy Kimmel started FB Unfriend Day - a day to clean out your Facebook friend list. If you're not sure where to start, here's who you should unfriend.

- The Let-Me-Tell-You-Every-Detail-of-My-Day Bore: If a typical day on FB for you goes something like this, I'm probably gonna unfriend you - "Just had Wheaties for breakfast.....Off to the dentist!.....I'm bored......What should I have for lunch.....Good night Facebook friends!"

- The Self-Promoter: Everyone has accomplishments. You don't need to pat yourself on the back EVERY SINGLE DAY.

- The TMI-er: Not everyone needs to know about your rash. And we certainly don't need a photo of it.

- The Chronic Inviter. Support my cause. Sign my petition. Play Mafia Wars with me. Which 'Star Trek' character are you? Ugh.

- The Look-At-Me-er: Constantly posting pictures of themselves trying to look sexy. Here's me in a red sweater. Here's me eating pizza. Here's me on the subway!
