You have to basically try to grunt that loudly right? No way that’s a subconscious thing. I mean it sounds like this guy’s straight up busting a nut out on the court. I’ve never played tennis, but I do know that in sports making a sound like that while hitting something just doesn’t make sense. You don’t hear Adam Jones grunting when he’s connecting with a long ball (or swinging through a pitch in the dirt), and Jordan Speith’s not making a noise when teeing off. The only people that it makes sense to grunt when they play a sport are the female tennis players, and that’s just to dish out boners to the men in the crowd.
