When one person poops into another person's butthole, and that person poops back into the original person's butthole. They then continue this, back and forth with the same poop.

When someone poops into someone elses butt-hole, and then they poop it back into their butt-hole, with the same poop. Forever.
"Like I'll poop into her butt-hole. And then she'll poop it back... into my butt... hole. And then we'll just keep doing it back and forth. With the same poop. Forever." Poop back and forth.

When two people line their assholes up facing each other, and one poops into the others asshole, and then the other person poops right back into the first asshole, and this goes back and forth for as long as they want.
Bob: "Me and this girl poop back and forth regularly"
Mike: "Holy shit, does it hurt?"
Bob: "It felt like I kept sitting in mud"
Mike: "Holy shit, does it hurt?"
Bob: "It felt like I kept sitting in mud"
