Definition & Meaning of "son of a sea-cook"in English

What is the origin of the term "son of a sea-cook" and how is it used?

"Son of a sea-cook" is an old slang insult used to describe a person regarded as contemptible, worthless, or unpleasant. It likely arose in English maritime culture in the 17th or 18th century, combining "son of" with "sea-cook" (a ship's cook, often considered low-status or untrustworthy) to create a colorful metaphor for lowly or objectionable character. The term is derogatory and informal, used in seafaring, literary, or social contexts to mock or belittle someone's worth or behavior. It is strongly insulting, though largely historical today.
