breaking sea level

To take a huge dump that while resting on the bottom of the toilet is large enough to form an island

That was a great dump; I just broke sea level!

Break Sea Level

To defecate in such a quantity that the turd(s) you produce rise above the water level in the toilet bowl.

After eating at the buffet I went home and had to break sea level. I feel much better now.
