hindu exclam Also hinda, hindoo [Prob. varr of hinder accidental interference with the ball in a game such as handball or squash.]
1981 Verbatim Letters NYC, One interesting term that came out of that game (Chinese handball) was cried out as, "Hinda" or "hindu." I would suspect that this is a corruption of the word "hinder" and was used if the ball accidentally hit some object. Today the term is "Do-over."
1987 DARE File NYC (as of 1960), In the games of Chinese handball, box ball, or king and queen, "hindoo" was called out if the ball went out of play owing to some type of interference.
Hindoo: A do-over during a game. It also refers to a funny bounce in handball. If the ball hits where the wall meets the ground, and bounces back in a slow high arc, that ball was a "hindoo" and not to be played, thus leading to a do-over.

This new method of ranking the college teams could be called a "Louie," like the "best-ball" gimmick in a golf foursome or the "do-over" we used to claim in sandlot baseball, or what we used to call a "hindoo" when the ball hit a nasty crack when me and Julio used to play handball down by the schoolyard.
