I may not be the first to air this idea, but I’ll give it a shot anyway. Google pr0nrank refers to the number of Google Image Search pages it takes to reach a NSFW/dirty/titillating image for a given search term.

winston churchill is 48; an image of a bodily organ near a face appears on the 48th page of results.

aficionado is 1. The first row of results contain suggestive bikini ladies.

In neither case, of course, was I expecting to find such images.
