If u know this one, your a tru genius!!!

Im looking for a rap/rock/hip hop song that came out last year(there about). All I can say is that the film clip had skaters and bmx riders with a crowd of people watching them as they went up skate ramps that were set up on a basketball court in a school gym, there was also some b/ball being played at the same time, the main artist was a black guy (with a green cap?)and im pretty sure a white guy as well. It was a really hyped up song. I think they were singing about "how good they are" you know how in some songs they speak themselves up? If you figure out this one based on this info you are trully the greatest...............
