aegrotat
They sported knowing,
and they sported ignorant;
they sported an ægrotat.‥
They sported an exeat,
they sported a dormiat.
--OED
(The original source of the poem is The Freemason's Magazine, [vol 4, p. 106] although the OED credits Gentleman's Magazine, December 1794. The full quote: ". . . they sported knowing, and they sported ignorant; they sported aegrotat, and they sported a new coat! They sported an exeat, they sported a dormiat, they sported their outer, a lion, a lioness, a cat, and a levant!" The article was signed: An Enemy to All Ambiguity.)
