[?] Meaningless words

The word "meme" has no meaning. In the last 24 hours, I have found it in a variety of contexts, and there is no way it has meant the same thing in all contexts.

It has been used to describe a list of questions, a graphic image, the use of a graphic image, a political term, the use of labels in political dialog, a group mentality, iconography associated with pop culture, and commercials.

What we are seeing here is the devolution of a great language into barbarism. Somebody please break out a dictionary before it is too late.
