Fake Jiu Jitsu was developed in dialog with Brazilian Jiu Jitsu, so I want to start with a broad definition of BJJ. There are, of course, many ways of defining it. I picked a definition that best highlights the differences with FJJ.

BJJ: A set of positions (top and bottom) and techniques (offense and defense) learned from a teacher, practiced by a student.

In one informal sentence, Fake Jiu Jitsu is:

FJJ: A pseudo-scientific approach to training jiu jitsu that trades the concepts of 'technique' and 'position' for a small set of 1st order principles, and the higher-order principles derived from them, verified through first-person experience.

FJJ Defined through its 1st-order principles:

FJJ: Using Turtle Space Control to maintain your ability to apply alternating Shotput-powered Bridge and Shrimp movements onto an opponent you are Connected to, Timed contrary to an established Pattern.

FJJ can also be defined as an Ecological Dynamics experiment:

FJJ: A set of constraints that reduces degrees of freedom by imposing restrictions on how you think instead of how you move.

Throughout this document, I'll be referring to Fake Jiu Jitsu as FJJ or FJJ2. FJJ2 is the latest version of FJJ, but in general the terms can be used interchangeably.
