In plain English, a cad is a man whose conduct is selfish, untrustworthy, or socially dishonorable. It is not mainly about stupidity; it is about character. The word often appears when someone has behaved badly toward another person, especially in a way that feels ungenerous, manipulative, or ungentlemanly.
Cad is old-fashioned and morally critical. It usually refers to men, and its traditional gendered flavor is part of the word’s history. Use it when the sentence needs a vintage charge of dishonor. For modern neutral language, use "selfish person," "dishonest person," or "untrustworthy man."
gentleman, decent person, honorable person, trustworthy man
