I have often heard the term "throw" used in badminton. What does it mean a player loses a point because of a "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.
Carry : An illegal stroke in which the shuttle is not hit, but caught and held on the racket before being released; also called a "sling" or "throw".
So if the shuttle is held on the racket before it is being released, it is called "throw".
The rules of badminton consider the following as faults:
- If the shuttle is caught and held on the racket and then slung during the execution of a stroke.
So it is considered as a fault.
I think there's a language barrier at work here. Jacob Jan Tuinstra's answer is interesting but misleading. The context of the question is how "throwing" can lose a point. Slinging or throwing the shuttle is a fault in the BWF Laws of Badminton, 13.3.7, page 8:
It shall be a fault: if in play, the shuttle is caught and held on the racket and then slung during the execution of a stroke
