Pretty much all through my entire school life, although it softened up around my last few years of high school.
I guess it's true what they say, kids who like to prey on others tend to know something's off about kids who are different, even if it's not obvious. I used to get picked on all the time in elementary school, teased all the time, beaten up constantly, till I started fighting back.
The thing is, I didn't fight back with fists, I'd just grab them by the wrists/collar, and throw them till they decided they were too tired/hurt to keep trying to punch/kick me. They'd often go get their buddies to try to help them, I could easily keep doing this to a group of 4-5 thanks to a very early puberty, coupled with a hormonal imbalance that made me about 6 foot 2 at age 12.
Shitty part is that they'd end up with all the injuries, which made it appear I was the one doing the bullying, got in shit all the time... Yeah, blame it on the gentle giant... Well, that was until a teacher actually seen all this happen. Some little shit thought it would be a good idea to take a length of tree branch to my back, which he did. I grabbed it from him shortly after, brought it between his legs, and lifted him into the air... and about 3-4 yards behind me, he landed on his face, and chipped a tooth. By then, the teacher that witnessed this came over, the 3-4 other little shits scuttled off, and I tried to explain myself to her, she said she saw what happened, and that I was just defending myself, and she finally clued in that it was pretty much the same deal all along. The little shit was bawling his eyes out, and since his little friends had bailed prior, I had to carry the little shit back to the school nurse, had him over my shoulder the whole way, making sure he felt every bump on the way (as my shoulder was kinda lodged in his gut) After that, people tended to stop trying to pick fist-fights with me, although the verbal abuse continued.
Once I hit junior high school, it all started back up again, but much worse, the teasing had turned to bigoted hatred, the guys caught up to my size, and I couldn't throw them around anymore. I had even gotten beaten up by half a soccer team because I punched some ass in the shoulder after he threw a slush drink at me, my older sister came and scared them away. The next day, the whole lot of them were calling me gay, ******, and the like. I told them that they really can't afford to be doing that, considering the whole soccer team were these arrogant French immersion students, that most of the student body considered pretty queer to start with, and that it wasn't helping their case. Interestingly enough... that got them to stop for the most part. (Maybe that's why they were being bullies? Because they wanted to show some sort of masculinity?)
High school was mostly uneventful in regards to bullying, I became a pretty big loner, and everyone seemed to leave me alone.
Even out of school now, I get the occasional bit of hate mail from people wishing some pretty horrible things upon me, because I'm trans, and that seems to bother people in my backwards little conservative, overly-religious town.
Being a transsexual, I mostly look back at these losers as people who ganged up, and beat up girls, really makes them quite pathetic.
