The term 'SLOB' is a slang term used to describe a lazy and untidy person. It is derived from the word 'SLOBBER', which means to be careless or sloppy. A SLOB is someone who is not only lazy but also untidy, often leaving messes behind them. They may not take care of their personal hygiene or appearance, and may not take pride in their work or home. Slobs are often seen as lazy and unmotivated, and may not take responsibility for their actions.
