Zombie

A zombie is an animated human body devoid of a soul, with no free will, originating from the Voodoo belief system.

In Fallout the word was used for themselves by Set's ghoul gangsters, 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.
