ahem - they are all boy crazy. There are levels of boy crazy.
Level 1: secretly dreaming about meeting or marrying a member of the current boy band that you CANNOT LIVE WITHOUT.
Level 2: squeeeeling or gigling when you see your boy crush
Level 3: asking your friend if she would talk to you your boy crush and then spend 2 weeks analyzing the conversation..
it goes on… you get my drift.
