MILLBURN, N.J.  The principal of Millburn High, New Jersey’s top-ranked high school, says it has gone on for a decade: annual hazing by senior girls who create a “slut list” of incoming freshmen for the first day of school. A dozen or more names are written on a piece of notebook paper, with crass descriptions, and copies are passed around  hundreds this year, some say.

“We’ve had girls  which is one of the bad things  obsessed that their names are on it, and girls who were upset that they didn’t make the list,” said the principal, William Miron. “It’s basically vulgar.”

And that is not the only type of hazing that goes on, some girls say. Seniors blow whistles in some girls’ faces and jostle or push them into lockers, leaving them afraid to come to school the next day.

These tales were out in the open on Friday after half a dozen parents complained to public school officials and a discussion of hazing on a private e-mail group for mothers made its way around this Essex County township.
