emulcion
A gadget used in Chinese homes like Nico's that releases a nightly stench so foul it knocks you out. Supposedly invented in 1782 by Estevan Quito (a common Spanish pun on the phrase for this little bench), it is made by boiling sewage for two hours. When the gas is released, no one can resist it and they hit the floor. It is shaped like a butt.
Your ass.
