Etymology

Origin of cad

First recorded in 1780–90; short for caddie (in the sense “a person who runs errands and does odd jobs”)

Explanation

A cad is a man who is not gentlemanly or honorable, especially toward a woman. He asked the waitress for her phone number and left you with the check? That cad! Also known as a rake, a scoundrel, a rascal, or a heel, a cad is not a guy you want to be around too long. The word cad came from the word cadet, meaning a "servant." Later cad came to be a derogatory term used by students at British universities, referring to boys from local towns. Don’t confuse the word cad with the acronym CAD, meaning "computer-aided design."
