Porta Blumpkin

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.

Why don't you come inside this porta potty and give me a Porta Blumpkin.

The Porta Potty Blumpkin

When one receives fellatio while defecating in a portable restroom or other rustic lavatory.

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