mephitic adj of, relating to, or resembling mephitis; foul-smelling
Right. Do Not Define a word employing a word I do not know. That is Not Helpful, Merriam Webster. Unless, of course, the word I do not know can be Easily Found (don’t you know how easy it is for me to get lost –and for how long– in the dictionary?)
But look! Here it is! Directly Below mephitic:
mephitis noun [L]: a noxious, pestilential, or foul exhalation from the earth; also : STENCH
Ah. Nice word. Nasty word. Definitely Effective.
Which sets me to wondering if it’s at all related to another word Very Close By on the page: Mephistopheles.
