Double Blumpkin 69 

When you're getting a blumpkin but the person sucking your dick is upside down so you can 69 but they also poop at the same time... this means their poop is either going to slide down their back and hit the floor, fall forward into your face while you suck and/or lick their genitals OR you'll get a diarrhea fountain all over their back and your face.

I wanted him to double blumpkin 69 me but he said he wouldn't do it unless I had diarrhea for the fountain effect.

Upperdecker Double Blumpkin

A man takes the upper-back of the toilet off and sits on it. A woman gives him a blowjob as he takes a crap in the back of the toilet. After crapping and the blow job is done, he puts the lid back on the toilet.

An unsuspecting person comes in later and uses the toilette. When they flush the toilet it fills with brown water from the crap the man took in the upper deck.

“I was over Al’s house and I upperdecker double blumpkin’d his toilet. That thing was flowing brown all day”
