I think he was referring to the fact that we CALL it secondhand smoke, but it's really just smoke, and we added a word in front of it for no real reason. I'm pretty sure he was NOT talking about its health effects. To add my own to this list: Seen, when used in the following manner: "I seen that", etc.
