Scatophiliac

Dean Swift, Jonathan Swift, Dean of St. Patrick's from Dublin, clergyman, was a great, shall we say, combined scatophobe and scatophiliac. He both hated and was fascinated by faeces.

Joseph Mallard Turner had a profound, if scatophiliac, attraction to fire at sea.

Like the exhibitionist, the scatophiliac wants his victim, the person on the other end of the phone line, to be shocked, disgusted, or horrified by his demeanor or words.
