I dunno... in 19th century Italy (when this painting was made (The Confession (Molteni))), a Catholic priest might have called this a "bodily perversion" in order to extract a fee for an Indulgence, especially if the priest believed it would be an habitual occurance.
if my art degree is worth anything, its for parsing the moral value of a meme (and booby Italian toast fetishes) in its historic context!
