Santorum saves a college student from using a pink bowling ball.

The most favorable explanation of Santorum's comment is that a generic pink ball provided by a bowling alley is most likely weighted and holed for a woman's hand.  You want a ball with holes positioned for your hand and with as much weight as you can comfortably handle.

Whether it is the actual explanation, who knows?

Bowling balls (and I say this as someone who bowls a lot) in public alleys tend not to be weighted or designed by gender, but for hand size. So Santorum was just being a douche.
