When you're banging a girl in the butthole, and your penis eats the poop in the girl's anal cavity. Then you pull out and pee a poop in a thin line, and you proceed to snort it like cocaine. The girl then puts her vagina into your nose and it eats the poop you just snorted, and then the cycle repeats until all the poop is used up.
