It is used by:
1. A famous supervillain who's been doing this since before it was cool.
2. A very old wizard-type fellow or Mad Scientist for whom this just comes naturally.
3. A bona fide psycho, in which case you'd better do some pretty impressive cackling.
4. A Genre Savvy Villain who does it because it's a classic villain maneuver.
5. A truly Magnificent Chessmaster who may or may not be an Anti-Hero, but almost always VERY LOUD.
