At a club in Glasgow, Scotland, two guys get ejected for harassing staff members inside and then look to pick a fight with the bouncers at the door on the way out. Never a smart idea.
The bouncers do their best to keep the disruption to a minimum but as the mayhem unfolds, things escalate quickly and a battle breaks out.
One of the bouncers is a Gracie Barra blue belt in Jiu-Jitsu; taking one of the troublemakers to the ground and immediately applying a Kimura from the North-South position.
The two guys eventually agreed to make trouble and were sent on their way. No police were involved.
The art is sometimes referred to as Gracie Jiu-Jitsu (GJJ), a name trademarked by Rorion Gracie, but after a legal dispute with his cousin Carley Gracie, his trademark to the name was voided.
Other members of the Gracie family often call their style by personalized names, such as Ceaser Gracie Jiu-Jitsu or Renzo Gracie Jiu-Jitsu, and similarly, the Machado family call their style Machado Jiu-Jitsu (MJJ).
While each style and its instructors have their own unique aspects, they are all basic variations of Brazilian Jiu-Jitsu. There are currently four major BJJ branches in Brazil: Gracie Humaita, Gracie Barra, Carlson Gracie Jiu-Jitsu, and Alliance Jiu-Jitsu.
Each branch traces its roots back to Mitsuyo Maeda via Donato Pires Dos Reis, and then through the Gracie family or Oswaldo Fadda. [Wiki]
