Hmmm.... This could mean two different things really... And there is no way for me to further analyze the situation unless this case belongs to me.....
This could mean that the guy really sees you as a sister and do not want to have a more intimate relationship with you. Id this is the case, there is really no need for you to read between the lines as he means what he says.
On the other hand, this could mean it's exact opposite. It is really up to the girl to read the signs and see what the guy really means.
Most guys, as we are aware, are insecure and do not take rejection easily. They find it hard to express their feelings (I am not saying that every guy acts this way okay?) and sometimes ends up saying the exact opposite of what they mean.
If this is the case then if he calls a woman sister it could be because he do not want you to see that he likes you as more than just a sister because he fears that you don't feel the same way about him. If he is this kind of man then it is up to you to save him as most of the time men don't really know what they want.
Another explanation would be that he doesn't mean anything about it at all. I am not sure how to expound this one so let me give you an example. Let us say that you and him are friends or a member of the same organization. In an organization, its members treats each other like a family (brothers and sisters) so if he calls you a sister in this scenario it is probably because that is what everyone calls you in your circle of friends. :)
Either that or he's very fond of you.
Yes.
She's your sister.
then she is a racist
It is slang or gangsta for kid or buddy.
It means You are Just Friends. Unless YOu want it To mean more.
* There are two terms for 'sister.' One is an old slang term used up until the 1950's. Example: 'Listen sister, I had this taxi before you.' If a person has a friend of the opposite sex and they refer to them as 'sister' then yes, that means that person is endearing to them; thinks of them as a sister with no romance involved.
He likes you more than just a friend sweetheart. Call him boo next time he calls you that and see how he reacts
she thinks of you as a great friend or a brother.
if it is a boy then they are flirting. if it is a friend then it is a nickname
rather its a joke, or there not dead
she is very special friend.
