    supernaculum — medieval Latin super unguem, "upon the nail." The sixteenth-century German and English drinking-table test for having drunk fair: upend the emptied cup over the back of your thumb; a single drop that rolls off the nail is honest, anything larger is wet-handed. First recorded in English in Thomas Nashe's Pierce Pennilesse, 1592.
