haunter
n.— «It started out innocently, as these things often do, with a few strings of pumpkin lights. Then I discovered the secondary market in anatomical displays. Medical-school skeletons with misaligned femurs don’t get sent to the dustheap. They are marketed to “haunters,” as do-it-yourself fright-makers are called.» —“Elaborate but affordable Halloween gadgets hit Web” by Denise Flaim Newsday (Long Island, New York) Sept. 20, 2007.
