That's lame. It's just the opposite. It means nothing. Most people say what when someone talks to him/her. No offense, but it means nothing. IT's just a reflexive action. Take it from someone who knows.
It means he likes her back.
that means probably her 2nd option.
It means that he is a cheater who wants three girlfriends at the same time.
no, she probably wants you to do it first cuz you're the guy
means he likes you, you stupid c unt
It doesn't mean they like you maybe they are bored and just wants to talk to you
It means you will receive texts (to your mobile phone) with updates.
What does XML mean in a text

If by "texts" you mean Closed Captioning, you simply have to turn that feature on with your TV.
