There is a four-letter part of the body (fitting the 'sodomists' part) and then a four letter word meaning 'orifice'. How this works with the rest of the clue, I don't know
Rossim and malone. Thanks for taking the trouble. ABUTTALS fits in nicely with my other answers. However it does seem too classy a word for Viz! I think that's it though...
I've set the occasional crossword and sometimes there is only one word that fits in with the crossers. It's particularly difficult with themed puzzles.
