I think mentioning bitcoin could be easier for newbs, maybe some businessmen with some experience in payment processing and finance could understand, but this is just not for everyday people.
People who have knowledge about payment processing would probably already know about Bitcoin.
I guess if you have to explain Bitcoin to newbies, you must remove complexities about how the underlying transaction works. They can treat it as a black box. As long as they understand how to transact, it is sufficient. Once they are comfortable with Bitcoin, they will explore the mechanics behind it.
