I have. I got beaten up, and once the bully had demonstrated his ability to beat me up at will, things got worse.
It is worth noting that one cause of bullying is a way for the bully to feel better about himself. In my case said bully had failed 2 grades, and so chose to pick on a smart kid who was not popular to make himself feel better.
Too bad you weren't able to use your superior intelligence to learn BJJ (there was no way to know which martial arts worked when I was growing up). If he got you down and suddenly his arm was broken and he didn't even see how it happened I bet he would have left you alone.
Very possible, but now the requirement is you have to fight back and win, not just fight back, which is probably asking a bit much in some cases. Some kids that get bullied even have handicaps, so this probably won't work for them.
