I feel the need to learn Romanian so I can curse at my step mom.
Why would you want to cuss at your step mom?
She is always yelling at me, I just want to show her.
It's not nice to curse at anyone, no matter the language. She'd be really upset with you if you did this.
I will do it because I don't give a flying f**k if I upset her
It seems like rather a large effort to be so petty. I think you should just talk to her and tell her how what she does makes you feel, if she can't respect you you can move out and get your own place soon.
