Several times but i'll shorten it down to two:
1) last December I was hanging out with my friends at their apartments and all of a sudden these girls come up to us. They're ranting about how stupid and fake my friends up and I'm like Whoa whoa whoa, if you want to have a problem with them you have one with me. Sadly, they didn't know about my really short temper and said something about my family. I didn't take any time to hesitate, I just jumped on two of them and swung. One of them ended up getting out of my grip so it was just me and the girl that talked ****. She went for my earrings and I was like K.. she punched my boob and I was like O.... She went for my mother****ing hair MIND YOU it's the most precious thing in my life, not fake, and I constantly take care of it. I ended up dragging her around the corner of the apartments (a wide space between three buildings) put her head up on an airconditioner and swung for dear life, poor gal thought she wouldn't get IT.

Luckily, I didn't get in trouble, no one pressed charges. Her mom was already pissed at her for her grades so she was already done.
2) I went over to my friends house for a sleepover without knowing who was invited, like back in June. So this girl that had a crush on my ex boyfriend was there and constantly talked about him. I was like

bitch what u up to. After a while of dealing with her I vividly remember telling her to shut up. She asked me why and I said, YOU KNOW WHY. She played dumb and I told her I'm not here for any ****ing games, please don't ruin YOUR night please. I can't remember exactly what she said but she made a catty remark.

after that I went to the restroom, took off my earrings, tied up my hair, and told her to go outside. (I respect my friends mom TEW much to fight in her beautiful house)
Anyways, she grabbed me for a good five seconds by my hair and punched me in the stomach after that I grabbed her by her ear and dragged her to the grass by my friends pool. Obviously I climbed ha and did the usual.

mind you I was in my pajamas the whole time. The difference with this fight was that it wasn't as harsh as the other one I listed.
