Macaroni, a dandy, originally a member of the Macaroni Club established in London about the middle of the 18th century. . Its founders had travelled in Italy, and introduced Italian macaroni into England; hence their name. They wore long curls and "spying-glasses," and were much given to drinking, gambling, and other fashionable vices. The Italian macaroni is wheaten paste, forced by great pressure into a pipe-like form.
