I'm gonna go with they are just disrespectful little *****. It's so annoying to hear a 9-13 year old always running his mouth and always calling much older people kids. But what can ya do, tis how these kids are being raised in this day and age, no respect whatsoever.
I would LOVE to be able to walk into the room while some little kid talks trash like that to me. If they came face to face with the person on the other end of the mic they would curl up into a little ball and cry like a baby.
