I'll be sincere and say I find the last one too scary. That's not a fight, that's lynching... I understand about the revenge feeling though.
Anyway, I used to get into fights for most of highschool. I was the kind of girl that wasn't noticed by anyone until they needed someone to bully - then I'd get up and kick their asses.They usually didn't fight back - they had some shred of honor, they wouldn't hit a girl even if the girl was brusing them.
The most memorable one, however, was against another girl. She had been insulting me all year long, both in public and in little paper notes, for reasons I didn't understand -up 'till that moment she had been a friend, so I kept trying to keep things friendly or at least polite.
I hit my limit when one day, in the middle of a group excersice, I screwed up (oh man was I clumsy!) and tripped. All laughed - you usually do when someone trips, and I wasn't particularly popular, but she started... well, celebrating, you could say.Laughing loudly, pointing, commenting with her friends how stupid I looked - "Can't you be any dumber? What a funny kid you are, you always make me laugh. Loser!" and so forth.
I re-took my seat with as much dignity (now that's something I had) and said to my friend next to me "I'm really feeling like slapping her."
She, thinking it was a joke, shrugged and said "Sure, why not."
So I got up and while the teacher was wondering whether I was going to the restroom or something I walked across the room and slapped the girl. Hard. For the record I practised Karate in those days - I knew how to hit. Her head was turned around and her lip started bleeding.
I went back to my seat and said, loudly, something to the effect of "Gee, now that felt good!"
The teacher basically had the biggest WTF face ever and the girl was crying. The rest of the group laughed and since I was a straight A's student (and my dad was in charge of the Secretary of Education) I didn't even get scolded.
The girl wore a bloody lip and a black cheek for a few weeks. Her mother didn't complain either. Maybe she didn't love her.
