Um…wow. Its a rap about jiu jitsu by MMA fighter Ralek Gracie.
He is the son of Rorion Gracie, he has a short but undefeated MMA career, and he teaches out of the Gracie acadamy, the orginization that brought you the online blue belt, and the pnk belt. They now bring you “G in a Gi”. This will finally bring BJJ the street credit it had been lacking before.
