'Hog-eye man' is #126 in Randolph's 'Roll Me In Your Arms: Unprintable Ozark Folksongs and Folklore' (p 401 of Vol I of Uni of Arkansas 1992 edition - edited by Gershon Legman). In his note to 'Careless Love' (#237 in Vol II 'Blow the Candle Out' p 648), Legman has this note:

... 'hog's-eye' and 'pig's eye', the vagina or its split "upright diamond" symbol. (Not to be confused with the nautical slang, 'dead-eye', the anus, or a Turk's-head knot in rope). 'Hog's-eye man, an inveterate wencher or 'cunt-hound', a man obsessed with women or sex, also called 'Jody'. See texts at No 126 above.
