Definitions, please

[Evolution]

Ok, I hear people talking about Marks, Smarks and Smarts. How do you define these?

If my understanding is right, a Mark treats the product like it is real.

A Smark knows what is going on, but still acts like they can't believe it.

A Smart knows what is going on, and just watches to see how things pan out on TV.

If this is right, then I'm a Smark

But if it's wrong, please let me know.

Thanks.
