Sister 

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!"

Somebody who has the same mother or father as you, can be half, whole, or annoying. Determined to be just like you, or bother you.
Also any female who is acting like a sister.

Sister 

God's worst screwup, made to teach brothers how unattractive and morally wrong the opposite sex really is.

My sister just PMSed all over me, in every way possible.
