A little research can't hurt since we're talking about the continuation of something that began 25 years ago.
"An academic definition of Lynchian might be that the term 'refers to a particular kind of irony where the very macabre and he very mundane combine in such a way as to reveal the former's perpetual containment within the latter.' But like postmodern or pornographic, Lynchian is one of those Potter Stewart-type words that's definable only ostensively --i.e., we know it when we see it. Ted Bundy wasn't particularly Lynchian, but good old Jeffrey Dahmer, with his victim's various anatomies neatly separated and stored in his fridge alongside his chocolate milk and Shedd Spread, was thoroughly Lynchian. . ."
