I don't meet to sound ignorant ... But what is this "march madness"?
[/quote]

It usually refers to the NCAA men's basketball tournament. Sometimes referred to as 'The Big Dance,' or just 'The Dance;' the broader term 'March Madness' also includes the end of the regular basketball season (and the crowning of 'regular season champions' in each conference); conference tournaments (smaller tournaments between teams that regularly play one another); the NCAA tournament (massive, single-elimination championship, which includes all of the 'Conference Tournament' winners and the best teams from the season, for a field of 68 competitors); and also the NIT tournament (played by teams that missed the 'Big Dance,' but still won lots of games -- sort of like an 'honorable mention' tournament).

Ironically, the 'Final Four' and the championship game are typically played in early April, because it takes a few weeks to narrow the field.
