Double Reverse Blumpkin 

The act where the woman is taking a shit on the edge of the toilet while the man, or another woman, is eating her out. An easier, but messier variation is where the woman shits on the man while he eats her out.

This is not to be confused with a Blumpkin, or a Reverse Blumpkin, which are two different, but closely related things.

The woman was tired of giving her husband blumpkins all the time, so she forced him into a Double Reverse Blumpkin.

bogwash blumpkin 

To balance on the seat of a toilet with your head down the bowl and your feet in the air, while both defecating and recieving fellatio from another man/women while he/she simultaneously pulls the chain.

I didn't feel like using the toilet properly or being the right-way-up, so I suggested to my girlfriend that we have a bogwash blumpkin
