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.

Snoricide 

The act of killing an extremely loud snoring person. This is usually done by nudging, pushing, kicking and loudly sighing the person to death.

"This is clearly a case of snoricide. He died as a result of futile efforts to get him to wake up and stop snoring. At times attempts to get him to wake up included kicking, poking, jumping on the bed and loudly sighing 'wake-up and stop snoring dammit!' to no avail. The outcome was inevitable."

Sayoricide 

When your childhood friend commits the dead. Usually done after confessing to her that you either love her or will always be her dearest friend. And you can never change what happens.
Never.
Never.
Never..

I just witnessed a Sayoricide, must have been DDLC.

Sodomicide 

Death resulting from sodomy.

(What a shitty way to die, or kill someone)

Sodomicide is rampant in prisons where Viagra is in abundance.

Sororiderby

The group of 3-4 mean girls who hold a position of power on small Roller Derby Leagues. These ladies were the freaks and geeks on high school who never fit in with the cool kids and may have been taunted by the pretty people. Now, finally, they are the cool kids who torture the new crop of Derby Girl wannabees, freaks and geeks-who in turn become their evil minions. They'll do anything for an XO from these evil sirens. Luckily, the power works only inside the confines of Neighborhood Roller Derby (small leagues that are afraid to step outside their Roller Rink). Nothing can stop them, except clean Derby Karma!

I'd give my right front quad skate nut to find a Sororiderby free Women's Roller Derby League!

"Drink the kool-aid and do what we say are we might let you get us some water one day, Fresh Meat!" said the Sororiderby High Priestess to her hypnotized minions

sororities and fraternities

When you cant make friends by yourself in college, so your parents buy you some.

Boy: "How are you liking the new school?"

Girl: "It sucks, I don't know how to make friends, so my daddy is sending me more money so I can rush in the spring and pay some sorority girls to be my friends."

Boy: "Yea, sororities and fraternities are the only way to go for us elite, yet socially inept good looking people."
