Redneck Blumpkin 

An even grosser twist on the blumpkin that I randomly thought of one day. It is when a girl performs a blumpkin on a guy when he is shitting in a port-o-potty/port-o-john. Rumored to happen at the most redneck of places such as county fairs, nascar races and tractor pulls.

Mary-Sue gave Billy-Bob a redneck blumpkin at the tractor pull. This caused all Billy-Bob's friends to immediately become jealous and wish they could get one too. Billy-Bob was later quoted as saying "I'm gonna marry that girl one day".

Fondue Blumpkin 

This is probably the apex of sexuality. It's when you have bad diarrhea while a female (or male I suppose if you are inclined) is giving you a blowjob and you remove your penis from his/her mouth and dip it into the chocolate toilet soup only to pull it back up and reinsert within her/his eager mouth for an extra saucy reentry. Pretty much a dream come true.

My boyfriend gives me the best fondue blumpkins after 4loko and Chipotle.

Smashing blumpkin 

The act of mouth humping a judy whilst taking a dookie.

I was taking a mondo poo and my boo thang was all horny like, "Me so horny, me love long time." So, I had no choice but to give her a smashing blumpkin.

Inverted Blumpkin 

There are two kinds of inverted blumpkins:

1. To masterbate while shitting on a girls face.

2. To take a piss while getting your salad tossed.

Susie wanted to try something new, so she gave me an inverted blumpkin instead of a regular blumpkin.
