Serin Gas 

*chemical that makes the victims spine turn into the shape of an S o.O *

*Used by nazi's, commie japs, and other ass cracks to harm innocent beings* ((also tested on animals))

"I threw my sister in a room along with a bottle of Serin Gas, She coughed and howled for hours before the bitch died"

sarin gas 

Lethal nerve gas currently in production in many countries. Causes the nerves to die which eventually (and painfully) leads to brain death.

I hope I don't get hit with sarin gas, that would really suck.
