Here’s the saddest news ever: Holly Grogan, a 15-year-old Catholic schoolgirl in Britain, jumped off a road bridge and killed herself last week, allegedly after a barrage of mean messages on her Facebook wall appeared. Her parents blame “cyberbullying” and said in a statement, “Holly struggled to cope with the huge pressures placed upon her by the modern complexities of ‘friendship groups’ and social networking. Every responsible parent will empathize with our constant battle to instill self-belief and confidence in our children.” [NY Daily News]

Hazing: It’s not just for Chuck Bass at the Skull & Bones Society anymore! High school girls in New Jersey are now pretending they’re badasses by putting younger girls on a nasty “slut list.” The New York Times reported that catty seniors at Millburn High School in wealthy Millburn, New Jersey have circulated a “slut list” on which they scribble dozens of names of “pretty and popular” incoming freshman with “crass descriptions” on loose-leaf paper. The school principal, Dr. William Miron, said the tradition has taken place for over a decade, but this year hundreds of copies of the “slut list” written up by sports team members apparently made the rounds in the hallways. Why is the Times calling this “hazing”? This sounds like full-on bullying to me.

A survey by the Workplace Bullying Institute found that most bullies are men—but 40 percent are women. While male bullies attack men and women, female bullies tend to go after their own kind, targeting other women more than 70 percent of the time.

My guess is that some women who want to feel powerful feel the need to dominate others, and lording over other women can be easier than commanding men. With the economy the way it is, people are trying to get ahead, and some are taking not-so-nice measures to get there. In case you’re not sure whether someone is bullying you, tactics can include being glared at in a hostile manner, being given the silent treatment, and having others fail to deny false rumors about you. Sounds like pretty catty behavior, doesn’t it?
