The expression “snake oil salesman” is one of the most colorful insults in the English language, and today it means much more than someone who literally sells a dubious medicine. A snake oil salesman is a person who promotes something as valuable, effective, or miraculous when it is actually worthless, deceptive, or seriously exaggerated. The expression can describe a dishonest salesperson, a charlatan, a con artist, or anyone making extravagant promises about a product, service, investment, or idea.
