A sexual act where the woman lies on her back, while the man squats over her. She sucks his dick while he simultaneously takes a shit on her. A combination of a blumpkin and a cleaveland steamer.
(Guy1): Hey man, how was the date last night?
(Guy2): It was awesome, I blumpland steamered her and their was corn in my shit!
Similar to the Blumpkin (taking a dump while receiving a blowjob) except this time your shitting in the top tank of the toilet.
After we entered the restroom, we disrobed, removed the top cover on the toilet. After I paid her, the prostitue gave me a blumptank. I bet the cleaning people were impressed.
