OP I'm not sure what you're asking.
I assume that you know that when people label a girl as a "tomboy", they're saying that the girl is behaving more like a boy than a girl. Of course, the assumption is that girls only like to sit quietly and play with dolls, and that all boys are into sports and dirt or whatever.
If someone specifically says this to you about your daughter, feel free to just ask them what they mean. Might as well put them on the spot.
