alpah girl

这是个新词，表示女孩中间有支配力的女孩；或者说欺负其他girls的女孩。有点象中文的大姐大。

英文解释：alpha girl (AL.fuh gurl) n. The dominant member in a group of girls; a girl who bullies other girls.

举例：Citing new research on teenage relational aggression, a flurry of articles and books have appeared in recent weeks trumpeting the existence of the ALPHA GIRL(a k a the "really mean girl" or the "queen bee"), a supremely confident, domineering and manipulative teenager, whose main appeal seems to be her stereotypically masculine behavior.
