How would you define Hip-Hop?

I’m really curious about how people who’s not too found of the genre would define it. Because of the way popular Hip-Hop is today, I completely understand if you think it’s ridiculous. Auto-tune and MySpace has really messed things up in my opinion. And I think it has become to much of a synonym with gangsters and pimping. Please name some Hip-Hop artists you like or have heard of also.
