canadian water-pluck
When your taking such a huge shit. That as soon as the heavy ass projectile hits the water it creates a drop big enough to go up and slightly in your ass hole. Therefore making the rest of your dirty business very wet and uncomfortable.
Yo dude, i was taking the biggest shit last week and when the huge thing fell in the water i got a canadian water-pluck, and now i still have that damn water in my ass and it moves around when i walk.
