Gumbo Over the Shakers
The act of fucking a girl or guy from behind and they shit on your penis with chunky diarrhea, and the person with penis inserted into anus has ungroomed pubic hair. The pubic hair acts as a screen catching the chunks and letting the watery mud flow down.
Dude, last night I was with Kandi - even though she didn't feel well. One thing lead to another and when I was banging her from behind, she totally shit all over my dick and pubes - it was definitely "Gumbo Over the Shakers".
