using the facebook wall to "instant message" in replacement of aol instant messenger or other such instant messaging programs

Someone who posts show results in their facebook status, ruining shows for people who recorded them using a DVR.

Facebook cool means you are friends with people you don't even know.

You are chating with your friend when; boom they are gone! No good bye, Mauh or kiss my ass. Nothing at all! At this point in time you are like WTF, wondering if there connection was bad or something happen to them? You sit there dazed and confused just to find out your "Friend" is an ass and does not feel like typing good bye. The term for this type of individual is Facebook douche bag...

An act in which one looks at a friend's/stranger's facebook profile, pictures, and recent activity. Everyone denies their involvement in this act (when in reality most people do it when bored), then in turn accuse someone else of doing it later.

A person that does this often is called a Facebook Creeper.

Someone who always comments on your facebook status, photos, posts, if theyre in a relationship, who confirmed their friend request. These people also always chat with the victim and they are the ones who start the conversation. These are the type of people who would write on another person's wall just to reply to the one you posted on their wall. See: Dick Rider, Kiss Ass, Kiss Up, and Suck Up.

someone who stays on facebook just to IM his/her friends once they log on and ruin their facebook experience
