We could describe what happens in this video, but perhaps a song would do it better:

Feel me up at the ball game / I caught a ball with my crotch! / Buy me some peanuts and cracker jack / Its the least you could do after touching my sack! / Feel me up at the ball game / Right in front of the crowd! / 'Cause it's one, two, third base you reached at the OLD BALLS GAAAAAAAAAAAAME!!!
