when something is so self-referential (i.e., meta), that it looses all meaning because it is too confusing to follow. A good example is the movie Inception.
"Dude, so how about I am making a movie about how I am producing a film about how went to the theater to watch a movie about a group of people making a movie about the film industry?"
"I'm lost in a meta fog, bro. I think you need to simplify."
