I have seen this several times during the regular season and "off-season"
games with boy's teams. Usually the girls know better and you do not see it. But it is always the Allen Iverson wannabe that puts the beads in the hair that forgets that he has to play a game. I never let them play, if they do not like it, so what. I usually tell them, "Girls cannot wear them, why should you?" They usually say nothing after that.
Peace
