Rush goalie is a variation of 
football (soccer) in which the role of the 
goalkeeper is more flexible than normal. The goalkeeper position is left unfilled until the ball comes near the 
goal. At this point the nearest outfield player will take on the role of goalkeeper.  Once the danger has passed the player in goal(the 'rush goalie') may then return being a normal outfield player again. 
Rush goalie is only played in informal football matches, usually by children, and often when all of the players wish to play a more active role in the game than the position of goalkeeper would normally allow.
