I did read it, but I also know that a lot of memes CAN be explained. In fact, most of them (at least the ones that I'm familiar with) can. I think your understanding of the word "meme" is a little inaccurate. "A unit of cultural information, such as a cultural practice or idea, that is transmitted verbally or by repeated action from one mind to another."
Many slang terms can be traced back to their roots, too, such as "groovy," "homey," "Catch my drift," and "square." It's really a matter of investigating. There's even a term that I remember hearing in an old Chip n' Dale's cartoon, in which Chip called himself a gay dog. It was a term used at the time that can be compared to playa'.
I think we ought to agree to move on from here.
Going back to the point of this thread, I'm thinking about looking into (the real) Liechtenstein's stance on many of the proposed subjects, such as marijuana and stuff. I think it'd make the panels more interesting that way...
