Barney: You want the girl to be above this line. Also known as the Vicky Mendoza Diagonal.
The Mendoza Line is an informal term named after either Mario or Minnie Mendoza, used in baseball for when a position player's batting average falls below .200 (some say .215). It is supposedly the boundary between extremely poor and merely below-average offensive production. Some consider it to be the offensive threshold below which a player's presence in the Major Leagues cannot be justified despite his defensive abilities.
