Friendship issue

I have this friend i made at the start of year 12 but I don't think I want to be friends with her anymore
These are the reasons why and I need some advice on what to do next:
- she talks about herself A lot: she is constantly talking about herself that one of my friends pointed it out saying he doesn't like her because she constantly talks about herself. At first I thought it was just so she could relate to conversations but then one day I was having a conversation with an teacher I knew and she was there and I kid you not for a whole hour she talked non stop and didnt even let me say anything when I had something to add. I would even try to talk in between pauses but she still talked over me and even when I was talking she talked loudly over me so then it sounded like we were shouting so I just stopped talking. She also says things like" let me tell you what I'm going to do when I get home" and constantly refers to her friends when she's talking about herself with me and my friends
- she keeps calling me and my friends losers even though I've expressed that we dont like it when she does
- everytime I talk about my culture she tries to correct me even though she knows nothing about my culture
- she lacks the ability to pick up on basic social cues so she just comes off as rude most of the time.
- she teases me for liking kpop even though she also likes kpop and is even more obsessed with it than me but has convinced my friends that I am the obsessed one so now they all tease me for it. And they even tease me for watching kdramas telling me I make" kdrama movements" and she instigates these convos by encouraging them whilst actively watching Chinese dramas in the common room everyday and I dont do that but suddenly im the kdrama obsessed one. I think my friends are more comfortable with pointing it out to me than they are to her.

Ok drop this friend also K-dramas are fire queen keep up the hobby fr
