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.
Jon: "Hey, did you hear Jack broke up with Jill?
Paul: "Uh, how'd you know that? Were you facebook creeping?"
Jon: "No, of course I wasn't!"

A few hours later...

Brian: "Hey, did you hear Jack broke up with Jill?"
Jon: "Dude, stop facebook creeping."

A Facebook creep is someone who passes all of their free time on Facebook, looking up details of someone they just met, someone whom they may be infatuated with, but this is not necessary.
A Facebook creep knows of all flattering and compromising pictures of a person, as well as where they are, and follows the developments on the person's wall closely, perhaps to spot a lover not mentioned in the relationship status.
Tory spends all of her free time on Facebook when she should be studying. She is a huge Facebook creep.

Curtis: "Tory! Did you see those new pictures of Chris?"
Tory: "Those were up yesterday. I love the one where he was hammered!"

Something we all do.
Person One: Are you facebook creeping again?
Person Two: Yes, yes I am. But that doesn't make me creepy.

A person who spends too much time looking at people's pictures, conversations, and information. They especially take the time to check out people of the opposite sex they have never met before or talked to before. Facebook creeps also have random conversations with people of the opposite sex who they would never talk to in person, and think they have some type of "game". A good facebook creep will start a relationship with the person who they randomly started talking to.
Person 1-Nick was talking to this girl in our hall who he never talked to before.

Person 2- What a facebook creepers!

Person 1- Can you believe Nick goes out with this girl who he met on facebook. That's not wierd or anything

Person 2- Ha,Ha! I'm sure this kid thinks he is the man now cause he has a girlfriend. Too bad the only reason he goes out with her is because of facebook.
