U.S. Army term for a mythical creature that clubs privates, NCOs, gurus, officers and anybody else nearby that has succumbed to the bad advice of the Good Idea Fairy. Usually the Common Sense Fairy visits during AARs, accidents, misfires, or any other SNAFU moment. The weapon she yields is a club that often brings forth reduction in rank, loss of pay, cool points, jail time and anything else the smacks one with common sense. Listen to the Common Sense Fairy!
Captain Corelli and his mandolin just got smacked by the Common Sense Fairy when it was found out that his good idea is being investigated by CID and IG.
