A zombie is an undead corpse, originating from certain pre-War religious beliefs and popularized by fiction films and entertainment. While it is sometimes used as a derogatory term for zealous cultists perceived to have no free will of their own, it is most often used by bigoted wastelanders as a deeply offensive racial slur referring to Ghouls. The corpse-like appearance of Ghouls, the slow shuffle with which the more decrepit move and the ignorance or unwillingness of some to differentiate between feral and intelligent Ghouls, have led to such slurs as brain eater and zombie. This also popularized the belief that Ghouls can only be killed by shooting them in the head. Ghouls in turn often refer to normal humans as smoothskins, while Super Mutants often use the term bleeders. Many posthumans, such as Ghouls and Super Mutants, suffer from inequal treatment by normal humans, ranging from name calling, racial segregation to outright hostility, in the most extreme cases even leading to lynchings or slavery. As of yet very few places in New California have managed to create a truly open, harmonious society where all races are accepted and considered equal. Racial discrimination is outlawed in the NCR, though as always societal viewpoints are slower to evolve than legislative ones. Nevertheless the ranks of the NCR military and Rangers are among the most diverse to be found and the status of posthumans is changing for the better.
