They're violent, disturbing, and for the most part, they involve kids.
Punching, kicking and whaling on each other -- then posting the video on Facebook for everyone to see.
And hundreds of thousands are "liking" it.
"It's kind of a new thing to videotape it and put it up. I think people try to use it as a rite of passage maybe in some ways, just to show that they're tough," says student Doug Read.
Fan pages with names like "You Got Knocked The (*#$%*) Out" and "Crazy Fights" show video after video after video.
"They don't understand the severity of it because they are hiding behind the computer. They feel a sense of safety as opposed to doing something bad to someone to their face," says professional life coach Michelle Phillips.
And if you think your kids would never be involved, think again. A video FOX 13 first showed you Tuesday was taken on a Pasco County school bus. It shows the victim, 16-year old Chase Cristia, an honor roll student at Mitchell High, viciously attacked by one of her classmates.
Pasco deputies say she was ambushed and beaten from behind.
Another student, who deputies say was in on it, whipped out a cell phone to record the attack and then posted it online.
"It hurts more that it was put on Facebook for everyone to see, not just the people on the bus. I get phone calls and text messages every hour, asking what happened, how am I," Chase says.
"Horrifying, horrifying to see it had gone to so many people," says her mother, Tracy Cristia.
The two girls involved in the school bus attack have been suspended from school and the Pasco County School District has opened an internal investigation into the incident.
The Pasco Sheriff's Office also arrested the girls. One is charged with simple battery. The other is charged as a principal to battery.
Phillips says helping kids build self-esteem and self worth is the first and best defense.
"The better that kids feel about themselves, the less likely they will engage in that kind of behavior. And that starts with us as parents. How are we speaking to ourselves and to others. How are we treating ourselves and others," Phillips says.
"I don't think it should be on Facebook because Facebook prides itself on being family friendly, and everything's private and restricts things like nudity, and it's just absurd," says student Brendan Carroll.
