redrum
Word used in the novel "The Shining" by Stephen King and in the movie based on it and directed by Stanley Kubrick.  "Murder" spelt backwards.  Also works on many other levels, being suggestive of bloodshed, wrath, inebriation, violence, a force that consumes people's lives like some satisfying drink, and something used to subdue the Native American tribes that form a subtext of the film.
