Just like any variation of the word blumpkin, this sensuous act occurs between two people who are in love with each other. A gentleman should climb into a dumpster, preferably behind a grocery store or fast food restaurant, begin shitting (pants are optional, but your ding dong must at least hang out the zipper). Then a close friend or whore will climb into the dumpster and begin to slob on the shitter's knob while he is pushing out all those juicy feces.
I was constipated after I ate at Checkers on Lewis Street, so, I walked in Blockbuster, but they wouldn't let me poo. Thankfully I stumbled across Zack's sister and a girl with the exact same name. I informed them of my condition, and they offered a Dumpster Blumpkin. So, that's how I spent my afternoon,between Checkers and Blockbuster, Dumpster Blumkining two ladies with the same name.
