To dump a load so big that it forms a pyramid several inches above the toilet's water line, often has the consistency of cement fresh from the cement truck. Can also be molten lava that explodes from your asshole, spraying the underside of the toilet seat. The horrible smell causes paint to peel off the bathroom walls and all of the house plants to wilt.
That poor bastard who walked into men's room nearly asphyxiated from the horrific smell of my anal holocaust.

When you fart more than you shit, and as you stand up, the fumes escape from the toilet literally suffocating you in your own gas chamber of a bathroom.
