Actually it's an insult to girls. Many female college and high school softball pitchers have a hell of a lot of steam on the ball. I certainly wouldn't want to hit against them. (This from a guy who's brother could pitch a softball in at 75 mph, as measured by a radar gun, well into his late 30s.)
I'd say Jacques throws like a Frenchman, or a wuss, but I repeat myself.
I think some people are confusing the term 'girlyman' with the term 'girl'. A girlyman is a man who is 'girly' because he lacks the features of a man, not because he possesses the features of a girl.
