postmodem depression 

The feeling you get when you haven't had access to the internet (i.e. facebook and twitter) for a long time, like several minutes.

(A family is on vacation)
Mom: Johnny, come to dinner!
Johnny: Fucking not hungry!
Mom (to dad): What the hell is wrong with him?
Dad: He's got postmodem depression; he can't update his facebook status.
Mom: But we have only been here for 15 minutes.

postmodem bipolar depression 

Unlike the previously mentioned in Urbandictionary 'postmodem depression' which is the feeling you get when you haven't had access to the internet for a long time, like several minutes. Postmodem bipolar depression is the feeling you get when your internet connection keeps going off: when it's up you feel happy and excited; when it's down, you feel sad, lonely and helpless. This can happen several times in a day.

I haven't seen your sister for days: I've heard she's suffering from postmodem bipolar depression.
