Peehole

Rhythmically contract and relax the muscles around your coochie and your peehole about 50 times a day.

And then, thankfully, the stream slowed down, until it was nothing more than a few loose dribbles shaking themselves free from her peehole.

Or maybe it does, if you believe the guy who claimed one somehow traveled from the water, along the entire arc of his urine stream, and lodged itself in his peehole.
