In ten-pin bowling, a right-handed bowler is supposed to make the course of the ball curve from the near right-hand gutter so as to strike the headpin (#1) and the pin just behind and to the headpin's right (#3). When a right-handed bowler instead causes the course of the ball to cross over the center-line of the alley and strike the left-hand side of the headpin and, often, the pin just behind and to the left of it (#2), this is called "Brooklyn" which is, mostly, I think, capitalized.
