Ninjaism

Ninjaism is a type of elite fighting technique, practiced exclusively by the USLR's ninja fighting force. Ninjaism is considered the best and most useful type of martial art (by the USLR). They believe it makes ninjitsu look like a rag on a stick.
The unfortunate truth of the matter is that the USLR has never actually fought any ninjas. Most ninja prefer making money for performing assassinations, and mercy killing mentally challenged people tends to be pro-bono work.

Unlike ninjitsu, ninjaism does not require years of training to develop proficiency. Also, unlike mixed martial arts, it does not rely or any grappling or ground fighting tactics. Instead, the genius who designed it (grand master Fred "Dragon's anus" Gimply) reduced it into two extremely efficient moves. The first involves taking large amounts of steroids. The second (and most effective) involves raging. Gimply observed the fact that people who achieve roid-rage tend to be unstoppable aggressive warriors similar to viking bezerkers. Therefore it doesn't really matter how well they fight, they are simply oblivious to pain, and kick peoples asses.

Trivia

• Only USLR ninjas are trained in this art
• A USLR ninja defeated a real ninja once in a pie eating contest.
