What is guerrilla jiu jitsu?

Guerilla Jiu Jitsu is Dave Camarillo's style of Brazilian Jiu Jitsu. Check their site: http://www.davecamarillo.com/ Jon Fitch is one of his black belts. (I first saw the refence to Guerilla Jiu Jitsu in his UFC 100 fight bio.) Dave wrote a book on the style and here is the summary off of Amazon: Guerrilla Jiu-Jitsu is a groundbreaking system of grappling that integrates the Olympic sport of judo with Brazilian Jiu-Jitsu, today's most sought after grappling art. These are the techniques and strategies that allowed Camarillo to devastate the competition at some of the world's most prestigious judo and jiu-jitsu tournaments and have led his students to more than a dozen victories in the Ultimate Fighting Championship. Guerrilla Jiu-Jitsu offers a leg up on virtually every opponent who refuses to stray from the parameters of his discipline.
