What is the origin of the term March Madness?
March mad is an obsolete term meaning 'being mad as a March hare' since during March (the breeding season) hares are wilder than at other times; hence the proverbial saying. The term March Madness was first used in 1963 in reference to humans. By 1991, it was used in the San Francisco Chronicle, "The nation is now in the middle of 'March madness', that time of year when the NCAA basketball tournament takes place."
