To explain something in a way that confuses things even more.
Because their constituencies wouldn't vote for them otherwise, certain politicians learn to clarifuscate early in their careers.
When my physics teacher tried to explain how to work the deadly tesla coil for the lab, he ended up clarifuscating me until my eyes were glassy and my drool was seeping onto my shirt. This resulted in me frying myself and setting the school on fire. Too bad I was dead to see the prison burn.
