The act of 6 or more different people each taking a shit in the same toilet, thus creating a revolting cocktail of excrement that will block the toilet and causing a pungent smell that will linger for an extended period of time.
A perfectly executed Anal Poxon will result in the waterline inside the bowl to be non-existent, making it harder for the waste to be flushed.

"That smells disgusting, almost as bad as an anal poxon!"
