Euphuistic

James Harvey, a prominent Methodist, published his Meditation among Tombs in 1745. It contained many a euphuistic sentence as morbid as the following: “Instead of sumptuous tables and delicious treats, the poor voluptuary is himself a feast for fattened insects; the reptile riots in his flesh.”

In English, curiously, the euphuistic use of “behind” (as in “Get off your behind”) to mean “buttocks” is turning this preposition into a body-part noun (which is rare).
