Facebook filter 

Eliminating information that is inappropriate or uninteresting from your Facebook posts.

I wish she wouldn't use Facebook to bitch out her friend. Does she not know all 300 of her friends can read it? She should use her Facebook filter.

facebook filler 

People you don't really talk to on facebook, but you just keep in there to increase your volume of friends.

example 1:
"Hot woman on your wall there, bud..."

"Yeah, she's nice.
Oh wow, I haven't talked to her in... a year now.
Hmmm, I guess she's just a facebook filler."

example 2:
"Wow, 974 facebook friends, hey?
Mostly facebook fillers, I presume?"

FOF (Fitter On Facebook) 

Fitter On Facebook.

It originated from the brisk streets of london, between a small group of friends. When seeing a girl from afar that you recognise from the social network know as 'Facebook' you say they looked fitter on facebook, FOF. This has been used as an inside joke between friends so that you can't be caught out when in public and we believe its time that the rest of the world should know about it.

Ask your self this are you a FOF?

What is that about, mate that girl is FOF.

She looks like she carries a heavy load, she was defiantly FOF.

That girl looks like she takes a dick, she looked FOF.
