Someone who constantly flirts/hooks up/plays head games with people they are friends with on Facebook. This usually involves posting several statuses that suggest they are about someone but no tags because there are several people they are messing with.
Did you see Carolyn CeeCee Reeds statuses? They were all about different guys.

Yea.. she's a Facebook whore.

When people have over 2000 friends on Facebook.
It's like sleeping with tons of men/women except it's on Facebook and everyone can see it.
Me: Hey Mary! How many friends do you have on Facebook? I just hit 500!

Mary: Oh I have 3746. I just cleaned out my friends list so it's a little bit small.

Me: You Facebook whore...

a person who comments on EVERYTHING and lurks on every possible status, picture, album, etc.

Either a girl or guy who adds everyone under the sun so that it looks like they have a ton of friends, but in reality they just look stupid because they don't actually know any of them. This said person with a ton of "friends" often has no real friends and no one really likes them because they are fake. They also like to creep on these people they don't know. Guys are the worst because they will facebook chat, message, and comment on pictures of girls they don't even know...LOSERS. Some facebook whores will even post pictures of themselves that are slutty so they can get attention to feel better about themselves. They shoudl just rejoin myspace and quit being annoying to all the normal people who use facebook correctly.
Whore: "Omg I added that kid on facebook yesterday."
Person: "So don't you know him?"
Whore:"ummm, no...I just wanted to creep on him."
Person: "Wow, that's pretty lame..you're a facebook whore. In fact, I don't even really like you."
