Well I am 12 nearly 13 and a girl I met this school year said that. At the time she said this she was sort of giggling and besides that that's all I know. Any ideas what this girl means(I am a boy)

It may even be an insult, depends on how she said it. Referring you are not cool. You are that age, what does the term meam ?

Of course 12 year olds can not really date. Not like you going to pick her up in your car and go somewhere on real date

She was probably just joking and carrying a conversation with you. Possibly not much serious meaning at all. You are at that age that you look for meaning in everything that's said by girls. How did you respond? Like her or something?

It either means that she likes you and likes that you are cool, or that she thinks you are a nerd and would like you to be cool.

We can't read her mind. We can only guess at what she is insinuating.
