2. Pertaining to or like a macaroni or fop; hence, trifling; vain; affected.
3. In lit., using, or characterized by the use of, many strange, distorted, or foreign words or forms, with little regard to syntax, yet with sufficient analogy to common words and constructions to be or seem intelligible: as, a macaronic poet; macaronic verse. Specifically, macaronic verse or poetry is a kind of burlesque verse in which words of another language are mingled with Latin words, or are made to figure with Latin terminations and in Latin constructions. The term was brought into vogue by the popular satirical works in this style of the Mantuan Teofilo Folengo (died 1544). It is probable that this use of the word has reference to the varied ingredients which enter into the preparation of a dish of macaroni.
4. n. A confused heap or mixture of several things.
5. n. Macaronic verse.
