I've heard white people refer to black peope negatively as a "Splib" which I have been told is worse then N*gger.
So I guess if it ends in ib then it's not racist.

Probably Chicago in origin, an extremely derogatory term referring to blacks, such as the black group that beat and robbed your brother on a public bus. In groups they tend to compete with each other in violence against white folk, always one cracker at a time. The lone splib tries to **** your mother alone at a CTA bus stop. Splibs, however, usually are informal and not at all gang organized, as the gangs have much more discipline, purpose, and leadership. When in splib mode, a splib never turns on another splib, but only whitey. Splib groups gel spontaneously and quickly disband after a bit of violent anarchy. It is impossible to come up with a more derogatory word. Somalia is civilized compared to the splibs.
"SPLIBS! HELP!! POLICE!!! RUN AWAY!!!!"
"What happened to you?" "The ****ing splibs got me." "How'd you get away?" "Well, they trashed me (folded in half and wedged into a garbage barrel) and took off with my sister." "WOW, pretty lucky!" "Yeah, that's about the first decent thing the splibs ever did."
"Hey, Mr. McGivney was robbed yesterday with a gun!" "Was it a splib?" "Naw, all the ****** wanted was his wallet."
