1. The multi-level marketing friend who starts everything she writes with, "today I'm looking for 3 people to join me in......."
  2. The friend who constantly announces they are cutting down their friend's list, so be warned, today could be the day they drop you!
  3. The redneck, gun-slinging friend you grew up with that still uses racist phrases when commenting on your page even though you clearly find this behavior an abomination.
  4. The snooze-fest friend whose most interesting posts are "morning, Facebook" or "happy hump day". Paint-drying is far more interesting.
  5. The fake fitness friend who every 3 months posts nothing but workout comments and photos for 15 days straight, and then does nothing until their out-of-shape ass decides to get with the workout program (yet) again.
