Everest the bowl
To "Everest the bowl" is when you take a dump so large that it rises above the water in the toilet. As in, the poo piled up and came up out of the water much like Mt. Everest rises above the clouds.
Man...I really had to drop a deuce. It was huge and I totally just Everest the bowl. What's an Everest the bowl? Yeah it's when the poo rises above the water like Mt. Everest rises above the clouds.
