How would one get one of those?

To a degree, there's proof to support this. However, it's not just because of Rap. It's because of the person themselves most of the time. I'm talking from first hand experience and with tons of examples being around me for years. Music can do this but it's only to blame to a certain extent. The person, their upbringing, parenting, whether they're weak minded, so many other factors come into play.

Yes. I agree that that's what you're doing.

OT:  I've stopped using MIC's in online shooters because of things like this. I also mute most players with mics. If you're not talking about the game, I don't know to hear your voice. Just another distraction.

Man I just wish this kid grows up in a inner city school so when she mouths off someone just whoops her dumb ass.

It's terrible to hear someone so young speak like that, especially with the parents right beside her. That's just impossible to defend, there was even no reason to do that.

this is hilarious! i want to talk to her.

Where?  I didn't see any parents in the video.

Kids have talked like that for ever. The only difference now is people can film it and post it online. Nothing new here.
