My younger sister says "shut up" when me or my family asks her to do something or try to tell her if she does something wrong. What to do?

That’s something for your parents to address and deal with, not for you. You’re right, that is very rude and disrespectful, especially to your parents. But if there’s no repercussions for her actions, then there’s no incentive to stop. Even if they’ve already tried things, those are obviously not working. They’ve lost control of the situation and need to gain it back. There are so many outlets online for parents, other people to talk with and methods to handle this.

You could slap her... mmm... whatever a Drill Sargent would do.
