Really?

I got called a ‘*****’ by my mom for laughing. I was thinking about her hitting her toe on my bed and burst into laughter. And in a coincident, the daughter of her enemy was outside looking tacky as fuck, so my mom just assumed that i was laughing at her. Here’s how it went.
Me: * burst into laughter*
Mom: what’s so funny?
Me: hold on *continues laughing*
Mom: you need to quit laughing at people because you wouldn’t like it if peoples talked about you
Me:im not laughing at her.
Mom: yes you are! and you didnt brush your teeth today, did you?!
(Remind you that we are outside and she is yelling throughout the entire conversation)
Me: yes i did
Mom: no you didnt
Me: Yes i did, how are you gonna tell me what i did!
Mom: *turns and around and slaps me* Don’t yell at me, *****!
Im a ***** now. So i who’s gonna hit me next in my future; my boyfriend when i get older?
I guess bitches don’t deserve to live. Goodbye, *****!
