That would be WyoW, not Kat, who said "scatological." Scatalogical refers to feces, poop, or doodie. I'm leaning toward "penilogical," myself.

Things seem to start out being about one thing, and frequently end up being about penises. Might it have once referred to a sailor, but been adopted as still another cute name for a wiener, schlong, trouser trout, lizard, ding-a-ling, heat-seeking-moisture-missle, etc?
