When you're feeling extremely happy (or occasionally awfully sad) that you can't wait til getting home to upload your facebook status, thus ignoring your family at all.
YOU: I can't believe it!I passed the exam!I graduated!!
FRIEND: oh,congrats dude! go home,your family must be anxious and wanting to hug you and celebrate!
YOU:no way man! I'm on the facebook countdown,,all I want is to upload my status.. My family will have time to celebrate then.
FRIEND: you freak!
