look up any word, like blumpkin:
 
1.
someone who suffers from leprosy...this does not mean that their limbs fall off, just that their nerve endings die, so they cannot feel pain. This means they can't tell when they are wounded, and often develop gangrene. That's when the limbs fall off.
it's ok to hurt lepers because they don;t feel pain. people with diseases aren't real people.
