2. A phenomenon in which many girls hang out with one or two guys. Sometimes either conscious or unconscious attraction to the males is present. This phenomenon is often noticed in the latter years of high school, and often involves girls realizing the value of smart, thoughtful, and sensitive guys that had heretofore had little to do with the opposite sex and may not exactly have been social butterflies.

-"Yeah, he's really developed a girl posse over the last year and a half. It's like they can't stay away from him."
