Writers employ the adjective "foetid" to evoke an immediate, visceral sense of decay and revulsion by describing odors that are both physically repugnant and metaphorically dark. It is often used to characterize slimes, stagnant air, and decomposing matter in confined or cursed spaces, thereby setting a mood of despair or doom ([1], [2], [3]). In many texts, the unclean, oppressive nature of a setting—whether it is a dank dungeon or a moral wasteland—is emphasized through descriptions of foetid air, breath, or emanations, elements that serve to heighten the atmosphere of degradation and decay ([4], [5], [6]). Moreover, the term sometimes extends beyond mere physical attributes, symbolically hinting at the underlying corruption or contamination of society or the self ([7], [8]).
