I kinda had that too, but only in middle school.
Personally, I was in and out of detention since the fourth grade, reasons ranging from not having my homework done (which was pretty much all the frick'n time) to being too much of a class clown or smart ass for my teacher's liking (which was also pretty much all the frick'n time).
When I was in the sixth grade, I was constantly being suspended for getting into fights a lot, which usually ended with me being punched, kneed or kicked in the nuts. Those kids were bunch of bastards, assholes and bullies and I simply just didn't take their shit and stood up for myself. After the sixth grade, things just sort of mellowed out and I didn't get into another fight until high school. Fortunately, I was much bigger at the time and it didn't last very long.
One mourning before classes started, there was this kid that was following me around where ever I went for about fifteen minutes, insulting me with every cuss word and dirty name he could think of, trying his best to goad me into throwing the first punch. Then he picked up a mostly empty coffee out of a trash can and threw it at me. In order to paint you a picture of what happened next, I should tell you that this guy wasn't by any means small. He was about six feet tall and I'd say a burly two hundred pounds or so. At the time, I was few inches shorter than I am now, standing at six foot three inches tall and weighing in at roughly two hundred and eighty pounds. I charged him and with my momentum, I slammed and pinned him against a near by wall with his feet dangling several inches from the ground. I then screamed in his face "LISTEN MOTHERFUCKER, I'M NOT INTERESTED IN FIGHTING YOU! JUST LEAVE ME THE FUCK ALONE."
I promptly dropped him like a sack of potatoes, storming off in a huff, only to be stopped by a teacher who sent us both to the assistant principles office. The security footage was all they needed. He got suspend for two weeks, while I got off light with a three day suspension. My dad was proud of me that day, so much so that he loved to share that story with anyone who would listen for years after.
From that point on, I never got into trouble at school ever again.
