dynamics

This is really interesting to me. I have never had any type of formal education in dynamics, so I may be way off on this, but I can't resist asking what may be a foolish question.
The original question asks for the center of rotation at the moment the rod is kicked. If the center was fixed, say on a pin, obviously it would rotate about the center. But, since it isn't, would not the acceleration of the rod at the moment it was kicked cause it to skid across the ice for a distance until the centrifugal force caused it to stabilize? If so, does that not change the center of mass for that moment?
