.......farcebook.
Lol, thats epic...I cant believe I've never seen/heard /thought of that till now...duhh! Definitely now my goto term for that along with Twatter.
Faceboob is just as fitting

That would imply that Farcebook was something nice.

Yeah, I usually call it fecesbook if I have to mention it at all, but you gotta switch it up from time to time.
