The person you would want to hate the most in every situation. Also the most annoying and mean person in the world, meaner than Kim Jong Un! Your sister is also related to you, in case your dumb and don't know what a sister is. Your sister can only be a very ugly girl. When a sister is a teenager, she will spend most her time on her phone and get mad at you for no reason. Sisters mostly call you names such as: " dumbass, cunt, doodoo, dumb dumb, and the most popular, fuck asss."
Sister : " Wut up FUCK ASS!"
Me: " Ummmm........ HI!"
