Something that must be given to a white person via a black person. This allows
said white person to say the N-word without trouble. A white person cannot give this pass to another white person, unless
said white person has an N-word pass, and is giving that pass to another white person.
In a nutshell,
black people give this to a white person to allow them to say the n word. You cannot give an n word pass if you do not have one yourself.
