In context, I believe that it refers to ‘male nudity,’ which is apparently merely one of the things* that one can encounter in Dante’s Inferno… and wasn’t there a version of this available for the PC? Not that I could play it right now anyway.
*The female nudity is, of course, more interesting – particularly if you’re aware of Dante’s sense of humor, which was rather… rugged for our more refined and pampered era.
