How should I deal with this young female coworker who constantly keeps mocking me?

So at my current job me and my coworkers have always had a good rapport. We're not exactly friends outside of work but at work we have fun and act like good friends. We banter a lot and roast the shit out of each other but it's all in good jest. I always look forward to going to work because of them.

However recently this 18 year old female coworker joined us. Just looking at her I thought wow she's cute. Not in a way of actually wanting a relationship type of cute just generally young and innocent looking.

But she quickly went from cute girl to hideous monster because of her personality.

When me and my coworkers were roasting each other for some reason she always kept targeting me specifically. At first I tried to brush it off but she continued to do it over and over.

Before we all roasted each other almost perfectly evenly so no one feels hurt or left out. But this girl, this child comes and ruins it.

I tried to brush it off at first but she just kept doing it. And worst part was everyone was laughing at her jokes too.

One day I had enough and in an angry tone asked her hey kid what the fuck is your problem with me? And my other coworkers told me to calm down that she's just a kid and she just laughed.

And now I'm here at work trying to not pull my hair out because of this stupid fucking kid. I'm almost 30 and getting constantly taunted by a fucking 18 year old girl.

She probably only gets away with this because she's cute if she were ugly people would be calling her out.

I hate her so fucking much and have no idea what I should do.
