Object ball squirt?

I'm pretty sure that none of the balls in a nine ball rack move more than a millimeter or so before they separate. If that's true, what you describe can't occur because the movement is not large enough to change the kiss lines. I think something more complicated happens in a full, tight rack.

I've heard 1/4" or more. I believe I read about it in one of Freddy the Beard's books.

That would require the balls to compress about that same amount. Pool balls don't do that.
