Probesome

Powder and pomatum hush it,— So cautiously must the thing be watched, Least, probesome, it should strike too deep!

I had locked her in a comfort cage along with several well-behaved animals, but when I reached inside with my poker, my probesome attempts at physical and mental reconnaissance were a tearful disgrace for both of us.

The theory makes total sense: the more probesome a male duck is with his penis, the more parasites he is likely to pick up, ergo the more parasitised is his pecker.
