sororicide

The act of or urge to fully mudrer one's sister (older or younger) as she has a certain skill and manages to nag, belittle, and generally attempt to control your life as she does not understand that she is not in fact your mother.

Dude, i'm totally going to commit sororicide if my sister doesn't get off my tits pretty soon.
