Zombie

A zombie is an undead corpse, typically devoid of a soul and with no free will, originating from Voodoo beliefs. In the Fallout World, the term generally refers to Ghouls, who very much resemble corpses, often as a derogatory term.

The first appearance of the word in Fallout was when it was used by Set's ghoul gangsters to refer to themselves, and was pejoratively used towards Children of the Cathedral cultists.

In Fallout 2, the word can be used towards Wooz and he appears to be deeply offended.

In Fallout 3, most ghouls are very offended by the term. It is commonly used by the bigots who live at Tenpenny Tower, and calling Roy Phillips or Mister Crowley a zombie may lead them to attack you. Mister Crowley will hire you to kill supposed ghoul bigots by shooting them in the head like they do in old zombie movies.

In the Fallout: New Vegas add on Dead Money, the Ghost People can only be killed by decapitation, similar to the old zombie movies.
