My character starts off as a bully and I can't think of an insult said in the first chapter.

Hi! Like I said in the title, my character is a bully. She constantly picks on the only person who puts up with her. Trigger warning for self harm, death of a parent and bullying ofc.

She wants to move out and asks if her friend wants to come, to shich she replies that she can't because she has to take her of her brother and her parents, but mostly her brother.

Her brother was adopted by the friend's father, after he was the sole survivor at a murder scene. Because of this incident, he self harms by scratching the lower part of his face constantly, as if the blood from that day is still there. So in turn, his wounds never get time to heal. The brother is around 15-16, Vivian is 17 and a half, and the bully is 21.

The the bully(who's also drunk) says this foul thing :

"you're not even 18! You shouldn't miss your childhood just because your daddy couldn't keep his d*** in his pants after your mom kicked the bucket! And don't even get me started on <blank>, he should have died a long time ago!"

What can she possibly call him? Thanks and sorry for the topic. Also if you have other ideas for this line feel free to comment!
