When you have a massive deuce that must come out when your at a big party. You remove the top lid to the toilet, and release all the poo into it. When done, put the lid back on, and walk out like nothing happened.

A modification on the "classic" upper decker. In a public toilet setting (where there are no tanks/commodes), you improvise and shit in the urinal.

to leave a nice steaming terd on the toilet seat, enhancing the savory odor for the next user of the john; especially irritating to females, dudes not so much. Not to be confused with a Back Door Bandit which involves removing the lid of the reservoir tank and much better balance
