tomboyish

You can't keep up such a tomboyish trick all your life, and now is a good time to begin, I think.

She was not a pretty girl, but was a tremendously healthy one--strong, well developed, and tomboyish in her activities.

She has dropped that hoydenish, tomboyish manner that was so offensive when she returned from the ranch.

She was not particularly drawn to merry, tomboyish Sahwah, because she was not musical, although they got along.
