Not blowjob, but Brazil Brazilian Jiu-Jitsu. It's not gay dry humping eithereven though you may find yourself getting sat on, and smashed so bad you can't breath, but that's only starting out. BJJ is a truly intelligent combat sport. I can confidently say that I can take on anybody who has no background in BJJ no matter how over powering they are. Last week I submission spared against a taller, fatter opponent who had about 100 lbs against me. He was worried about trying tokill me, and the only thing I worried about was knocking shit over after I sent him crashing backward into a can of trash. The only thing I can compare it to is Chess, and you can't play chess if you don't know the moves. You can't swim if you don't know how to. Dont take karate. BJJ is not karate. It is a combat sport, and training tool for elite fighting forces. If anyone ever should find themselves interested in taking BJJ please do so. It will give you confidence, and separate your silly theories from reality in regards to fighting. Just make sure that the class is certified by a recognized creditably. I recently started going back to class for BJJ.
