When someone, more an online acquaintance than a close friend, greets you on facebook chat or another messaging service with a 'hi, how are you?' and then proceeds to say nothing else (occasionally a 'what are you up to?' MAY follow).
how are you-er: hey
how are you-er: hows it going?
how are you-er: good
how are you-er: what are you up to?
you: DONT TALK TO ME IF YOU DONT HAVE SOMETHING TO SAY. I ONLY ADDED YOU AS A FRIEND SO I CAN STALK YOUR HOT FRIENDS PICS.
