It's a play on words if you've never seen or heard of the Cartoon Samurai Jack.
Ofcourse Jack also refering to the old, Jack The Ripper.
Ofcourse it blows to someone not as familiar with the martial arts or oriental culture. Basically I follow Bushido, the "way of the warrior" and the life-style/conde of conuct that the samurai obey.
Obviously there are no samurai today, but in a sense martial artists are the contemporary samurai of today, as we do battle. Martial arts preaches self wisdom, defence, serenity, frugality, tranquility, peace, strength, respect, honor.
It gets a lot more complex, if you did understand you'd appreciate the name more, it's made for me anyways, not for you
I come from a familly of martial artists and am one myself
