The opposite of sexin. It is known to make people shorter. If some people were to have sex, their sexin levels would go through the roof. They would need unsex to bring it back down. To make it easier, cigarette companies started shoving unsex in their cigarettes. This is why people smoke after sex.
Look how short that midget is! his parents must be full of unsex to make him that short!
