I have often heard the term "Throw" used in Badminton. What does it mean when they say they lost the point because of "Throw"?
In this particular context, the word "Throw", could also be interpreted differently. Here it's meant to describe the mis-behaviour of players in a match (could be in other sports as well), to deliberately lose a game for their benefit.
Most recently, during the Olympics of 2012 held in London, four pairs of women's doubles badminton players, were excluded from the tournament because of "throwing" the game.
So if the shuttle is held on the racket before it is being released, it is called "throw".
So it is considered as a fault.
