Definition & Meaning of "slob"in English

What is the origin of the term "slob" and how is it used?

"Slob" is a slang term used to describe a person who is dirty, untidy, or lazy. It likely comes from the 19th-century English word "slobber," meaning to drip or behave in a messy way, and was shortened to label people who appear careless or slovenly. The term became common in informal English by the late 19th to early 20th century. It is derogatory but everyday, often used casually in social or domestic contexts to criticize habits or cleanliness rather than to deliver a severe insult.
