A more thorough explanation:

Definition: Puffing is when someone exaggerates or makes an overstated claim about a product or service to try to sell it. This is different from fraud, which is when someone lies about a fact to make a sale. Puffing statements are opinions and not facts, so they cannot be relied upon. However, if a puffing statement goes too far and becomes a false statement of fact, it could lead to legal action.

• "This car is the best on the market!"
• "This is the most delicious pizza you'll ever taste!"
• "This product will change your life!"

These statements are examples of puffing because they are opinions and cannot be proven. They are meant to persuade the buyer to make a purchase, but they cannot be relied upon as factual information.
