You need to let go of your ego and see the reality in this situation. You don't have to fight. You also cannot learn how over the internet in two minutes, it takes time and training. The only thing I can do to help is encourage you to avoid fighting. If you fight, you might lose, but when you avoid, you never lose. Be smart and stay safe and don't fight.
Now go forth, and don't fight.
Your mom said what? Lady you need a better role model.
Don’t fight, and especially don’t fight a girl that is a experienced fighter. I feel weird about these how do I win against experienced and trained fighter. The girl has sacrificed hours and hours of her free time to become a better fighter. If a person who sacrificed no such thing was to be able to just beat her don’t you think that would be like cheating the universe? It’s like asking, 'a girl got an amazing prom dress for $5000 and I would like one better for free. Where do I get one?'
If 'not fighting' is not an option you are pretty much on your own. Girls are vicious fighters and they fight dirty. Guys have an 'honor' code which gets them in trouble for not doing what they should have been doing. Girls just go at it and anything goes. So I think you are in deep doodoo and might want to reconsider your options.
If you are a guy fighting a girl is a lose/lose situation. If you lose, you lose, if you win you lose. Make her laugh, try flattery, be cute but whatever you do avoid a fight with a girl.
So i am suppose to be fighting this girl who fought & had experience of fighting. She asked to fight last year but i said no But im am not scared of her but i am scared of getting beat up and what people would say if i do. So i always fight my 13 year brother and beat him but it seems really diffrent to fight a girl. Can yall help me or tell me how to start the fight off because even my mom said when i see her just pluck (bang her) but it seems wierd hitting someone hard . And not fighting isnt a option
