To wear regular clothes in lieu of a spandex costume and cape. Derived from the HanoverSuperman of Hanover, PA (Scotty Bolton), who regularly goes out on the town in a Superman costume and/or Superman cape. Examples of his wardrobe can be found at myspace.com/hanoversuperman. On the rare occasion that he is seen in regular clothes, he is said to be dressed as Clark Kent (in disguise from his Superman persona).
"Hey look there's Scotty. He doesn't have the suit on tonight, he must be Clarkin' it!"
