Teenage gossip used to be scribbled in notes passed during class. Crude jokes were confined to the locker room.
Now snide comments, inside jokes and offensive language can explode online through new, quickly evolving outlets, where it can live on and be seen by thousands. The aftermath can ruin reputations, jeopardize jobs, disrupt classrooms and lead to lawsuits or criminal charges.
The controversy that flared last week in Rogers over a student's inappropriate tweet about a teacher was the latest example of the phenomenon, which has become common among high schools but still catches some administrators and parents by surprise.
"It's really natural for teens to want to be able to express whatever they want without being held accountable for it," said Shayla Thiel-Stern, an assistant professor at the University of Minnesota who studies youth and social media. "Teachers, parents, adults in general can tell them over and over again to manage their digital footprints, but they still don't always think it applies to them."
The result is a frustrating game of cat-and-mouse for parents, who fear that teens might make a very public, and long-lasting mistake. Schools, meanwhile, need to maintain a positive environment, while trying to teach impulsive teens how to safely use technologies that can spiral out of their control.
While many adults have learned to watch Facebook, teens are moving to Twitter, Instagram and Snapchat. And anonymous outlets, like the website ask.fm and parody Twitter accounts, offer a tempting but not foolproof veil for teens who know they shouldn't put their names to inappropriate comments. Those accounts, such as @612confessions on Twitter or the now shutdown "Rogers Confessions" on ask.fm can quickly become cesspools of profanity and sexually explicit language.
"There definitely are people that tweet stuff that's not appropriate," said Matt Miller, 18, a senior at Cretin-Derham Hall. "I personally don't because it's scary to me what the school would see."
