He explains (ed. 2, 1521) that the ‘macaronic art’ is so called from macaroni, which is ‘quoddam pulmentum farina, caseo, botiro compaginatum, grossum, rude, et rusticanum’."

Oxford English Dictionary -

"You that were once so Ĺ“conomick,
Quitting the thrifty style Laconick,
Turn Prodigal in Makeronick.
(Denham Dialogue 33)
