Get the Upper Decker Demolator mug.The very intimate act in which the male lover delicately removes the top cover on the porcelain tank of a toilet. Next he will mount the the tank and begin to defecate. Now the female lover gently sits on the toilet seat facing her male partner. The act begins when she also compenses to defecate while orally accepting his genitalia.
I knew she was the ONE when she pulled me into the hotel bathroom and introduced me the amazing upper decker double blumpkin.

Get the Upper Decker Double Blumpkin mug.its where you turn off the water on the toilet before someone takes a poop and you take a diarrhea in the upper water chamber. Then when a person sits down to take a poo, it lands on the porcelain and sticks, then when they go to flush it shoots diarrhea out. causing a horrible situation

Man 1. Boo boo has been gone for awhile
Man 2. He's probably taking a shit
Man 1. He farted before he left so likely
Person in question....we need to leave
Later admits he put his shitty underpants in the tank of the toilet of a public setting to avoid being embrassed
Now their shit covered under pants are worse then discovering actual shit in the tank
The upper decker delux
