Back to ghouls.
A ghoul is a (folkloric) monster associated with graveyards and consuming human flesh, often classified as undead. The oldest surviving literature that mention ghouls is likely One Thousand and One Nights. The term was first used in English literature in 1786, in William Beckford's Orientalist novelVathek, which describes the ghūl of Arabian folklore.
By extension, the word ghoul is also used in a derogatory sense to refer to a person who delights in the macabre, or whose profession is linked directly to death, such as a gravedigger.
