An extremely large, wide and machine like pole. Known to be more rugged than the AK-47, a Pakistani penis is known to inflict damage on anything it may encounter. It was said that if a Pakistani penis was to be dumped in the ocean, water levels would rise exponentially more than if the polar ice caps melted based on it's sheer weight and size alone.
Dude, I'm going to take a swim in the ocean. Don't blame my Pakistani penis for your neighborhood flooding.
