In plain English: A cad is an untrustworthy man who acts selfishly and shows no respect for others, especially his friends or family.
"The rude man in line was clearly too well-dressed to be just an ordinary cad."
Usage: Use this noun to describe someone who is rude or disrespectful in an arrogant way, often implying they lack proper breeding. It functions as a countable term for specific individuals rather than describing behavior alone.
The word cad is short for the term "caddie," which comes from the Scottish usage of the French word cadet. Originally meaning a younger son or junior officer derived from a root related to "head," it entered English with its current sense as an unrefined young man.
