asscrack sandwich

A sex position in which 2 naked men's hairy asses lay parallel to one another and simultaneously take a large bowel movement, then the 3rd party involved eats it out of the "buns" lengthwise (creating a hamburger bun effect) while piling the goods on their eyes, cheeks, nose, and lips in a slow deliberate motion. The 3rd person then regurgitates the mass and starts the process again, depositing the matter where it originally came from, like mustarding a juicy hotdog.
