Putting someone in 'facebook jail' refers to hiding their status updates b/c they (a) annoy you or (b) really fuckin' annoy you. This has no bearing on how you feel about the person, only how you feel about their thoughts contaminating your news feed. Okay, maybe it has a little bearing on what you think of the person, and whether or not it was smart to add them in the first place.
Homie, you are one step away from being put in facebook jail. Your status updates are fucking retarded.
