maccaroni (fashion)

A macaroni (or formerly maccaroni) in mid-18th-century England was a fashionable fellow who dressed and even spoke in an outlandishly affected and epicene manner. The term pejoratively referred to a man who "exceeded the ordinary bounds of fashion" in terms of clothes, fastidious eating and gambling. Like a practitioner of macaronic verse, which mixed English and Latin to comic effect, he mixed Continental affectations with his English nature, laying himself open to satire:
The macaronis were precursor to the dandies, who far from their present connotation of effeminacy came as a more masculine reaction to the excesses of the macaroni.
