Worst thing I did is....well, I dunno maybe breaking my leg or something or maybe adding bad words to my sentences like "Hey shithead, how's things going for ya?".
So one day when I was seven, I was playing hockey, and I decided to switch from defense to goalie for a game, and I felt really sick. A guy shot a puck right at my stomach and I puked all over his face and helmet.
Thats true self defense. sorry it was more about throw up.
I've almost paralizedd a guy in football, I've flipped a guy for trying to take out my legs at the drinking fountain I put someone in a sleeper hold untill he passed out cause we kept calling me names I was 8.... One time i got really high or drunk i can't remember and i peed on a cat.
when i was 8 i hit this guy in the top/back of the head with a cinder block chunk corner piece, and it knocked him down, and there is still a blood stain from all the blood. He was my friend but we got into and argument over something about i splashed water on him, and then he threw a rock at me and missed, then he saw my pick up the chunk so he started running, and i did an adrenaline lob and it was one of the longest throws i ever did do, and it hit him right on the head, and then me heart skipped a beat as he fell down, i went into my house, i thought i killed him. he is alive though he is ok he never held anything against me which i find surprising, i have grudges against peeps who haven't done anything near as bad to me, not physically at least.
