The act of getting a blow job while taking a shit on the toilet inside a Porta-Potty. Very similar to the plain BLUMPKIN. Just watch out for the blue water.

Get the Porta Blumpkinmug. While at the Grateful Dead Concert, Hoover gave me The Porta Potty Blumpkin, also known as a hippie blowie shitbomb.
