Intentional wrongdoing, especially on the part of a
politician or other public figure - although not limited to them alone;
well-thought-out mischief;
criminal masterminding; the process of using invention to work in order to craft new methods of wrongdoing.
Certain politicians have gone above and beyond pedestrian
politics and have become disciples of creative malfeasance.
The mayor of Podunk has transmuted the
art of creative malfeasance into a science; he's been in prison
3 times for it, too. And he just got re-elected.
