facebook scab: someone who adds random people they don't know as friends. usually to bring their friend count up to seem like they have a lot of friends
guy 1: "hey man, do you know this guy..........-.......? he just sent me a request" guy 2: " no man, i dont think i do, he's probably just a facebook scab,ignore it"
People who follow trends on facebook like posting celebrity doppelgangers, bra colors, stupid quizzes and name definitions from urban dictionary on their status, thus clogging up the urbandictionary site for those of us who just want to look up things like twat-snatcher.
Man, that dude is such a facebook sheep. There's not a trend he doesn't buy into.
God, all the facebook sheeping is driving me f-ing nuts. Like I care that she's got on a pinkbra. Gah.
