A variation on the Rock Island Plunger. Once again, during a three-way in which one member must be a male. In this case, instead of having normal solid stool the shitter must have diarrhea. The person with the explosive diarrhea fills the mouth of the shit-receiver, then the male inserts his penis and mixes the fluid around the second party's mouth.
In another variation, if the male has the capability for multiple orgasms, he will spooge in the fluid first to make it look like a Hostess Cupcake before he inserts. This act is also known as an Eskimo Pie.
After Seigfried, Roy and Boy George finished doing the plunger, they went to Taco Bell for burritos. Seigfried came down with explosive diarrhea and proposed not wasting the occasion and trying out the Rock Island Mixer because the plunger was so fun.
A favorite of college students in Ohio.
