When a black person knows a white person well enough that s/he will let him use the word "nigga" around him/her. Note that it's always "nigga," never the other way, and if overused niggamission can always be revoked.
"Hey, Tyrone, can I borrow your Strictly 4 My Nnnnnn... uh, that 2Pac CD?" "Oh come on, dog, you know you got niggamission."
