When you recieve a "run of the mill" blumpkin, however, you end it by forcing the givers head into the toilet bowl on which you sit, shoving their face into your fecal matter...
"She gave me a dunkin blumpkin, and her face was covered in shit!"
The act of receiving a blumpkin while in a Dunkin' Donuts Franchise.
Friend#1: "Dude, I heard that Jim was at Dunkin Donuts the other day and had to shit. After he went in some slut followed him and gave him a blumpkin in there"!
Friend#2: "Yeah dude, I was there! He totally got a Dunkin' Blumpkin".
a dumpkin blumpkin is combination of receiving a blowjob while sitting on the toilet taking a crap. after you finish cumming inside the mouth of the lucky male or female you take their head and dunk it up and down in your fecal matter. this sexual move usually works best with the beer shits or any kind of diarhea for that matter. once finished with the dunkin of the partner usually a hasty exaunt is quite necessary.
Because the party was extremely crowded Willma and Dan went to the restroom to hook up. Dan sat down on the toilet in order to comfortably receive a blowjob; little did Willma know what was in store for her. Dan began shitting uncontrollably at the same time he ejaculated into her mouth. After ejaculating in her mouth Dan in a diarrhea induced rage then forcefully pushed her head in and out of the diarrhea ridden toilet bowl. Dan is such a badass because he gave Willma a dunkin blumpkin
and didn't go to prison.
