Taught my 3 year old sister brainrot

I(15m) taught my baby sister brainrot, as a joke. I'm glad she's not swearing but at the same time she's been barging into my room shouting skibidi toilet before closing the door on my face and running away. There are countless days where she will look me dead in the eyes and go 'what the gyatt/sigma'. I'm going insane. Can't she just hop on cocomelon and take on their sayings instead of shouting rizz in the hallways? How do i fix this?

Edit: me asking for help is a joke, baby sister being brainrotted as hell isn't
