Polish rap awesome, funny, or totally dumb?

I LOVE Polish rap. My entire family right now (me, fiance, kid) is Polish and we love the rap! Not only does it have a great beat and meaningful lyrics, but the videos are hilarious because they all look like wiggers. Here's the catch: my 13 year old goes to school and talks about it and the other kids think he's weird. Anyone have an opinion on Polski rap?
