(Japanese) Jiu Jitsu is most defenetly the best martial art there is. The objecitive is to weaken your opponent by kicking and punching. After that you throw him/her on the ground and choke or hold your opponent to make him/her give up.
Unlike karate you dont have to bow to every fucking thing in the room.
Cockney slang for "hey". Also a british style of music, named so after the band Cockney Rejects who first used it in their lyrics, although Sham 69 was the first Oi! band. (not correct without an exclamation mark!)
