As with most men, there is a corner of my mind that is forever sophomoric. Here dwells the ineradicable prediction to snigger at fart noises, to appreciate practical jokes, and to wallow in bad puns like a blissful pig in an especially mucky mud bath.
This is why I always guffaw whenever anyone uses the word "titular," a fussy adjective I have defined as meaning "breast-shaped" since my early teens. In my defense, I present the similar sounding word "tubular," which I initially encountered around about the same time as my first hearing of titular.
Furthermore, I don't think I've ever heard any speaker say titular without a slight hint of risque frisson in their voice, so how I can be expected to respond with anything but a, er, well, a little titter.
