It depends on where & when you listen to it. I wouldn't recommend listening to it in public or around small children, elderly people or people in general that may be offended by it.
I agree with @Kahili... I have seen a lot of people doing that...
No a lot of people do, it doesn't define who you are.
No, i dont see why it would be a bad thing.
It's not really a good thing....
K thanks!
