fopnoun [ C ] Annie had always wondered what Fanny could see in a silly, trifling fop like Cyril. Courtesy he holds to be the vice of fops, and the manners of society mere hypocrisy. He was the fop of the school, wore the nattiest of garments, patent-leather shoes, gold watch, bosom pin, seal ring, and was blessed with a nice little moustache. I do not mean fops and dandies, but true gentlemen.
