Seems a bit strange but have a look at these...:crying: Is there a message they are trying to convey?
i usually do that once in a while, usually after a poorly executed shot (i'm in position early, and i still end up doing something wierd with the shot), or just simply a bad decision that ended up with a flurry of drives or smashes and me and my partner on the defensive and ducking for cover. its more of a "blaaah" than anything else.
Pete Sampras used to do that a lot during his playing days. Worst of all, I used to imitate that during my junior days!
