Pigeon Water
Pigeon Water is the water that drips off of the roof of buildings when it's raining. It is basically a rinsing of the bird shit that is on the roof.
When I caught my cousin being a dumpsterdick, there was pigeon water falling on him.
Water Pigeon
Another word for duck
I was rowing the other day when I saw a Water Pigeon having a go at a flock of land ducks
