Used when "facebook" seems to take ages to do stuff, like chatting or uploading photos etc
I couldnt chat on fuckbook last night, it was going too slow.

An alternate name for Facebook when a slutty female decides to take trashy/clothless pictures in order to get 30+ likes. These unfortunate attention whores are usually bashed because of their trashy actions due to mental issues, attention seeking problems, and/or they were molested or raped as a child or fantasize about it. These type of people ruin Facebook. These type of people deserve no respect. Total scum -____-
Example 1: A girl who decides to put on a bikini and take pictures of her bare body to seek the wrong kind of attention.

Example 2: A girl who poses in a slutty/trashy way, almost like a porn star or worse.

ETC.

Dialogue...

*Alex browses through Facebook and spots a picture of a girl who is 99% naked*

Alex: Wtf? Dude, this chick needs to put some clothes on. This is Facebook, not Fuckbook. If I wanted to see porn, I'd go to Spankwire!
